For XLPE insulated power cable, either chemical method or physical method is method is employed to
transform the molecular structure of PE from chain into three-dimensional network, i. e.
thermo-plastic PE is transformed into thermosetting XLPE. After cross-linking, the thermal and
mechanical properties of PE have been greatly improved while its excellent electrical property are
still retained.
The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is
900C which is higher than that of paper, PVC or PE insulated power cable. The cable has the advantage
of simplicity in construction, lightness in weight, convenience in application besides its excellent
electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with
no limitation of level difference along the route.
According to the standards of IEC, in the last few years, We have supplied XLPE cables to the Chinese
urbon power network reconstruction project, Beijing Capital International Airport, Beijing West
Railway Station, CCTV Station, Anshun Power Plant, Qinshan Nuclear Power Station, Ertan Hydroelectric
Power Station , Beilun Power Plant, Yimin Power Plant, Yangzhou Second Power Plant, Shanghai Subway,
Bao Steel Group and Yangzi Petrochemical Company, etc.. The products were given highly evaluation
from customers.
