Waterproof outdoor electrical cables are used in high temperature or high pressure environments for a good reason:
● Low flammability
● Resists oxidation
● High insulation resistance
● Exceptional vibration resistance to protect the mechanical conditions of the internal conductor wires
● Can be drawn down to extremely small diameters, providing fast response times when used in temperature sensors
● Can be formed/bent in the field without causing short circuits between the sheath and the internal wires, or between wires
● Can be easily sealed around when used as extension or control cables in critical environments
Construction of Waterproof Outdoor Electrical Cables
Waterproof outdoor electrical cable is made by placing copper rods inside a circular copper tube and filling the spaces with dry magnesium oxide powder. The overall assembly is then pressed between rollers to reduce its diameter (and increase its length). Up to seven conductors are often found in an waterproof outdoor electrical cable, with up to 19 available from some manufacturers.
Since waterproof outdoor electrical cables use no organic material as insulation (except at the ends), they are more resistant to fires than plastic-insulated cables. Waterproof outdoor electrical cables are used in critical fire protection applications such as alarm circuits, fire pumps, and smoke control systems. In process industries handling flammable fluids waterproof outdoor electrical cable is used where small fires would otherwise cause damage to control or power cables. Waterproof outdoor electrical cable is also highly resistant to ionizing radiation and so finds applications in instrumentation for nuclear reactors and nuclear physics apparatus.
Waterproof outdoor electrical cables may be covered with a plastic sheath, coloured for identification purposes. The plastic sheath also provides additional corrosion protection for the copper sheath.
The metal tube shields the conductors from electromagnetic interference. The metal sheath also physically protects the conductors, most importantly from accidental contact with other energised conductors.
Waterproof outdoor electrical cable is a specialized type of cable used in high temperatures or harsh environmental conditions because it has low flammability, even when operating at high temperatures. It resists oxidation and enables precise measurement.
The metal sheath that clads waterproof outdoor electrical cable helps to protect the thermocouple wires from oxidation when used in chemically active or wet environments. Corrosion resistance makes mineral insulated cable ideal for use in areas where failure and replacement could be dangerous or even impossible. Waterproof outdoor electrical cable is used in nuclear plants to monitor core temperatures. It would be extremely dangerous if the temperature controllers were not receiving accurate readings, and it would be difficult to repair or replace cables in that environment.
The mineral fillings in waterproof outdoor electrical cables provide excellent non-reactive insulation, preventing the thermocouple wires from contact with each other or with caustic substances such as oils, solvents or water. This helps to ensure that the thermocouple probes remain accurate, critical in applications such as heat treating or sintering where the quality of the product could be adversely affected by temperature fluctuations.
The insulation in waterproof outdoor electrical cables does not burn, which makes it ideal for applications where fire could be catastrophic. Medical devices, power plants, and oil rigs are examples of places where installation of waterproof outdoor electrical cables makes operations safer.
Molten metal molten metalsince the thermocouple probes are protected from contact with other electrically active wires by the insulation, they are not readily subject to malfunction or inaccurate temperature measurements. Carefully calibrated to meet international standards, waterproof outdoor electrical cables provide accurate and precise temperature measurement over long duty cycles with little or no loss of accuracy.
Because of the mineral insulation, waterproof outdoor electrical cables can operate in high-temperature conditions with no loss of accuracy. This makes them ideal in kilns, firing ceramics or heat treating metals or in any high-temperature process. Waterproof outdoor electrical cables retain their accuracy even during and after exposure to high temperatures, so they are ideal as a thermocouple probe in these operations. In addition, for industries such as medical devices or aerospace where safety standards are strictly enforced, process deviations could result in life-threatening quality issues.
Components of Waterproof Outdoor Electrical Cables
Waterproof outdoor electrical cables, are cables in which conductors or wires are enclosed by a metal jacket and insulated with hard-packed Magnesium Oxide (MgO). This basic construction provides high-temperature capability, exceptional electrical isolation, and physical protection for the conductors especially when subjected to harsh environments.
From the outside in, waterproof outdoor electrical cable consists of:
Metal sheath
Metal sheaths can consist of a number of different metals including 304, 310, 316, 321 Stainless Steel (SS) as well. In the most extreme cases, a customized sheath can be manufactured to withstand temperatures up to 1150°C (2102°F).
Conductor wire
Conductors can be made from a variety of materials, the most common include thermocouple alloys, copper, nickel, nickel-plated copper, constantan and others. The number of conductors will vary from 1 to 6 or more, depending on the application where it will be used.
Magnesium oxide (MgO)
MgO is used to isolate the conductors from the external sheath and from each other. This is a great material to use due to its dielectric constant, rounded grain structure, high-temperature capability, and its chemical inertness.
Can a Waterproof Outdoor Electrical Cable Be Direct Buried
Waterproof outdoor electrical cable is an ultra-reliable, extremely robust wire. It is suitable for the most demanding applications that include instrumentation and power in hazardous locations, outdoor use for services, feeders and branch circuits, nuclear reactors, and extremely high ambient temperatures.
Waterproof outdoor electrical cable consists of one or more (up to 19) copper conductors inside a continuous copper sheath, which provides excellent corrosion and mechanical protection. It also serves as an equipment-grounding conductor.
The copper conductors inside the copper sheath are separated and insulated from one another by a dry magnesium oxide powder that is introduced during the manufacturing process.
Waterproof outdoor electrical cable is permitted in all locations except where the copper sheath can be damaged either mechanically or by corrosion. In underground runs, the cable must be protected from physical damage. And there's a need for additional protection when the cable sees conditions that are destructive or corrosive to the copper sheath.
Waterproof outdoor electrical cable resembles flexible copper water pipe in that it can be carefully bent around obstacles and formed to make angle turns, as long as the minimum-bending radius is observed. The radius of the inner edge of any bend is to be not less than five times the external diameter of the metallic sheath for cable not more than 0.75 in. In external diameter. For larger cable up to and including one inch in external diameter, this ratio must not be less than ten times the external diameter.
The highly compressed refractory magnesium oxide powder is effective at what it does. But it becomes conductive if moist, and there will be line-to-line or line-to-ground short circuits. For this reason, the installation will fail if the copper sheath is corroded or otherwise damaged. Even a pinhole break in the outer copper sheath will compromise the circuit.
By the same token terminations require special materials and labor-intensive workmanship. The copper sheath is stripped back and a compression gland fitting is attached. Plastic sleeves are used to insulate the individual copper conductors. Then, an epoxy resin is mixed up and poured into the compression gland so as to realize a water-tight seal. If this procedure is not done to perfection, water will infiltrate and cause the circuit to fail.
Prior to installation, in storage, cut ends of the cable must be sealed to keep out moisture. As long as the integrity of the outer sheath and terminations is maintained, type waterproof outdoor electrical cable may be used in nuclear reactors, hospital operating rooms, high temperature areas, and most critical applications.
Where not exposed to touch and not PVC sheathed, type waterproof outdoor electrical cable may be operated at a continuous temperature of 250 °c. It will withstand an intermittent temperature of close to the melting point of copper, which is 1,083 °c. The refractory magnesium oxide powder is not damaged by that amount of heat.
How Hot Does Waterproof Outdoor Electrical Cable Get
In addition to protection against aggressive chemicals, waterproof outdoor electrical cables can withstand temperatures of up to 1000 °C and are resistant to both moisture and heat due to the outer sheath. This resistance is an important safety aspect, especially in potentially explosive atmospheres.
Waterproof outdoor electrical cables are used to cover applications that require high temperatures (e.g. chemical, petrochemical, oil and gas industries). The moisture and chemical resistant waterproof outdoor electrical cable can be used for process heating and temperature maintenance on pipelines, vessels, cryogenic storage tanks, power plants, machinery and equipment.
