IEC 60228 is an International standard issued by the International Electrotechnical Commission (IEC), whose full name is IEC 60228: Conductors of insulated cables Conductors of insulated cables. This standard specifies the conductor requirements for power cables, control cables and communication cables with rated voltages not exceeding 450/750V, including conductor material, structure, size, resistance and test methods.
IEC 60228 standard defines a variety of conductor types, such as solid conductor, stranded conductor, flexible conductor, etc., and their cross-sectional area, resistance value, conductor structure, etc., are specified in detail. These regulations ensure the quality and performance of cable conductors and provide a unified technical basis for the design, manufacture and inspection of cables.
The standard is widely used worldwide, and many countries' cable standards are based on IEC 60228, such as China's GB/T 3956 standard is equivalent to IEC 60228.
FAQs
Can XLPE cable be buried?
XLPE cable is made of a thermoset material, which means it is highly resistant to heat, moisture, and chemicals. This makes it an ideal choice for applications where the cable will be exposed to harsh environmental conditions, such as underground or underwater installations.
Which is better, XLPE or PVC?
XLPE provides greater tensile strength, elongation and impact resistances compared with PVC. This cross-linking process also enhances the material's resistance to oil and chemicals even at elevated temperature; this makes XLPE a popular pick as insulation for LSZH Flame Retardant or Fire Resistant cables.
Does XLPE cable need to be in conduit?
XHHW-2 Wire, also known as XLPE wire is a general-purpose wire that is suitable for applications in conduits, raceways, feeders, and branch circuits. It is also often found in power distribution systems in industrial, commercial, and residential buildings.
Is XLPE the same as PEX?
Automotive ducts and housings: PEX also referred to as XLPE is widely used in the aftermarket automotive industry for cold air intake systems and filter housings.
Is XLPE water resistant?
3 XLPE insulated wires and cables have excellent mechanical, waterproof and radiation resistance properties, so they are widely used.
What is XLPE insulation used for?
Common applications of cross-linked polyethylene (XLPE) are in building plumbing (or pipework) systems, as insulation for high voltage cables, and as an alternative for polyvinyl chloride (PVC) and copper tubing in water pipes.
What is the thickness of XLPE insulation?
We can manufacture XLPE starting from 3 mm up to 140 mm thickness.
What type of foam is XLPE?
Cross-linked polyethylene (XLPE) and Ethylene-Vinyl Acetate (EVA) foams are fine celled, chemically cross-linked materials with a micro-cellular structure. This type of material has a smooth surface, great shock absorption, and chemical resistivity.
What is XLPE made of?
XLPE cable is made from polyethylene (PE) as raw material, which is cross-linked by special electronic accelerators (or chemical methods). Cross-linking technology can change the molecular structure of polyethylene, thereby greatly improving its insulation performance.
What is XLPE equivalent to?
XLPE (Cross-Linked Poly Ethylene) insulation is found in XHHW, or RHH/RHW conductor types and generally exceeds the specs of standard building wire like THHN/THWN, which have simpler PVC insulation, but have a Nylon (the N at the end) jacket that is used to resist abrasion when pulling.
