Heat Resisting(Flame retardant) Power Cable

Heat Resisting(Flame retardant) Power Cable

1.Scope ofapplication

It is used as power transmission cable for electric equipmentsof rated voltage 0.6/1kV or lower in bad environment or thatwith high temperature.

2.Executive standard

Enterprise standard

TICW/03-2009

3.Performance in Usage

1: Rated voltage Uo/U: 0.6/1kV

2: Max.working temperature allowed by cable is 200C forcable with fluoroplastic insulation and sheath,105C for cablewith fluoroplastic insulation, 105C heat resistanc and PVCsheath, and 180C for cable with fluo- roplastic insulation andsilicon rubber sheath.

3: Max temperature of cable conductor is no more than 250Cduring short circuit (The longest lasting time is no more than 5s).

4: Temperature for installation is no less than -15C.5: Bending radius of cable as followsIt is no less than 20 times that of cable outer diam- eter forcable with single core It is no less than 15 times that of cableouter diameter for cable with 3 cores6: Power cable with fluoroplastic insulation and sheath hasgood features of chemical corrosion resis- tance hightemperature resistance and flame retardance.

4. Type and Description

 Type and Description in Table 1

Table 1

Note: 22 means steel tape armor “22" should be changed into “32” for cable with steel wire armor (if needed).

5.Specification of Cable

“core number * nominal cross section” stands forcable specification. Please see the following table 2 forcore number and nominalcross section
