The conductor XLPE insulated power cable is produced through chemical or physical methods sothat the product is considerably improved in its mechanical performance, thermo-ageing performance and adaptabity, and bears fine electrical performance. It possesses such unique characteristics as the conductor’s high temperature in operation, simple in structure, small in outer diameret, light in weight, convenient in use and free from the restriction of level difference of installation, lt is fit for power distribution and transmission netword of 6-35kV.
(1) Flame retardant cable
Flame-retardant cable in addition to GB/T 12706-2008 standards, its fame-retardant properties conform to GB /T 19666-2005 standard requirements are divided into A, B, C, D four different types of flame-retardant, A, B level for the best-type flame retardant property, C-level for general-type flame-retardant cable, users can select according their requirement, It is also can be made according to BS,DIN,AS/NZS,ANS etc.
(2) LSZH flame retardant cable
LSZH flame retardant cable in addition to GB/T 12706-2008 standards, its non-halogen, low smoke and flame retardant properties should conform to GB/T 19666-2005 standard requirements, its flame-retardant properties are divided into A, B, C, D four different types of fame-retardant,A, B level for the best type lame retardant property,C-level for general-type flame-retardant cable,customers can select according their requirement It is also can be made according to BS,DIN,AS/NZS.ANS etc.
