Cross-linked polyethylene insulated power cable not only has excellent electric, mechanical properties, but also has powerful
resistance against chemical corrosion, heat aging and environmental stress. Its structure is simple. The long term operating
temperature is 90℃.It is convenient to use and can be laid with no restriction of different level.
Our enterprise can produce both flame retardant and non-flame retardant series of XLPE power cable.
Scope of voltage grade and core number and cross-section
- a) National standard
D.C Resistance of finished cable at 20℃ per km is not more than the following:
Service conditions and operation parameters of Cable
A) Max. conductor operating temperature: 90℃
B) Short Circuit Temperature:250℃
C) Ambient temperature: 30℃
D) Soil temperature: 20℃
E) Depth of laying in direct : 0.8m
F) Thermal Resistance of soil : 150℃.cm/W
G) Thermal Resistance of ducts : 120℃.cm/W
Our XLPE Power cable can be produced according to our works’ specifications, which are equivalent to IEC, DIN, BS and ASTM, and its some indexes are superior to standards stated above.
