AdministratorIs XLPE the same as EPR?
Like XLPE insulation, EPR insulation is suitable for many higher voltage applications and whilst its dielectric properties are not as good as those of XLPE it does have some important advantages over XLPE including extra flexibility, reduced thermal expansion, and low sensitivity to water treeing.
What is a 66kv cable?
XLPE is an abbreviation of cross-linked polyethylene. This has been recognized world-wide as excellent dielectric material for wires and cables. It first went into commercial production in the 1960.
What are mv cables?
Medium Voltage cables, or MV cables, is a category defined by the International Electrotechnical Commission (IEC) as having a voltage rating of above 1kV up to 100kV.
What does EPR cable mean?
Ethylene Propylene Rubber
2. EPR Cable Specification. Ethylene Propylene Rubber (EPR), whose full name is cross-linked ethylene-propylene rubber, has the stability of oxygen and ozone resistance and partial discharge and has excellent cold resistance, maintaining good flexibility even at -50℃.
What is EPR cable insulation?
EPR or Ethylene Propylene Rubber is a copolymer made from, as indicated by its name, ethylene, and propylene. It’s also called an elastomer. This material is mainly used in electrical cables for insulation as its dielectric strength is higher than both ethylene and propylene separately.

What is XLPE wire used for?
XLPE cable can be used for plumbing, mining, and various electrical applications. Cross-linked polyethylene cables can also be found across the chemical industry and within the commercial and residential heating industry.
Where are EPR cables used?
The prospect of flame retardant ethylene-propylene rubber cable material. EPR has been widely used in power cables, mining cables, marine cables, motor wires and device cables, and other heat-resistant and high-voltage products, the use of about 10 % to 15 % of the total amount of rubber in the cable industry.
