Fire-Resistant XLPE Underground Cable
XLPE cable
XLPE is cross linked polyethylene material and PVC stands for polyvinyl chloride insulation. Both XLPE cable and PVC cable are the most popular cables. While sometimes we need to make a right choice between the two insulated cables especially when we need to choose a kind of Low voltage (0.6/1kv) Cables in a project. Therefore, it is of vital importance to differentiate XLPE cable and PVC cable.

Application field
These cables are used for power supply in low-voltage installation systems, and are suitable for installation in indoor and outdoor, cable ducts, underground, power and exchange stations, local energy distribution, and industrial plants without mechanical damage.
Advantages of XLPE cable
As the structure changes, XLPE has obtained excellent electrical properties. XLPE cables also have higher overload capacity in emergency situations. XLPE cable is an ideal choice for power transmission and distribution because it has high corrosion resistance in contaminated atmospheric environments and has better resistance to chemicals and corrosive alkalis. In addition, it can withstand vibration and thermal shock
XLPE insulators will not melt or drip even at the temperature of the soldering iron, and have increased flow resistance and improved aging characteristics. Compared to PE insulators, another advantage of XLPE insulators for LV and MV cables is improved water tree resistance.
