Executive Standard

The products is manufactured based on the GB/T standard 12706. 1-2008.

Application

The products are used to transmit and distribute power on the A.C. power

line, rated voltage 0.6/1kV. The flame retardant power cable is used for the

application that require flame retardant performance. Fire resistance power

cable is used for those applications in populated areas which demand on

fire resisting performance, such as high-rise building or big shopping mall.

Using Features

①The maximum long-term operating temperature of conductor is 70℃.

When short circuit (the lasting time should not more than 5 seconds), the maximum temperature of the conductor is 160℃.

②The minimum ambient temperature in laying is 0℃. It should be preheated if the ambient temperature in laying is below 0℃.

③The permitted bending radius of the armored cable should no less than 12 times of the overall diameter of the cable or at least 15 times for those cable without armor.

④D.C. resistance of conductor should comply with the stipulations of GB/T standard 3956-2008.

⑤Flame retardant or fire resistant characteristics; Flame-retardant and fire resistance cable are manufactured based on the GB/T standard 19666-2005.
