0. 6/1kV PVC (Cross-Linked Polyethylene)

Insulated Refractory Power Cable

Uses:

The product is suitable to be used for electric transmission line or industrial equipment that are required to be with fire-resistant property and used at the places for fixing or laying, with 0.6/1kV or less power frequency rated voltage. And the highest allowable long-term working temperature of cable conductor is (PVC/XLPE) 70 0 C/90 0 C.

When short circuit occurs, the highest allowable temperature of cable conductor is as follows:

PVC Cross Section of Conductor ≤ 300mm 2 ----160 0 C

Cross Section of Conductor >300 mm 2 ----140 0 C

Finished cable should stand the power frequency AC voltage test: 3.5kV x 5min.

Flame retarding refractory cable also can be manufactured following the Standard of GB/T18380.3-2001 according to the requirements of users.

Refractory performance should be in conformity with the requirements of fire-resistance test for Category-A and B specified in the Standard of GB/T19216.21-2003 and IEC60331-1999.
