Application of cross-linked polyethylene insulated control cables

The use of different cable types is also different, so it is necessary to clarify their own needs in order to find the appropriate cable model. Then, the following is to introduce the application of cross-linked polyethylene insulation control cable.

Cross-linked polyethylene insulated PVC sheathed control cable is suitable for distribution equipment with AC rated voltage of 450/750V and below as the connection line of electrical instruments.

Use features:

1. Laying temperature and minimum bending radius: no pre-heating is required when the laying temperature is not lower than 0 degrees; the laying is not limited by the drop, and the minimum bending radius: the cable without armoring layer should not be less than 6 times the cable outer diameter Cables with armored or copper shielded structure shall not be less than twice the outer diameter of the cable; flexible cables with shielded structure shall not be less than 10 times the outer diameter of the cable;

2, working temperature:

The long-term allowable working temperature of the cable conductor is 90 degrees. In the short circuit, the maximum temperature of the cable conductor does not exceed 250 degrees and the duration does not exceed 5 seconds.

3, cable insulation resistance:

At the highest rated temperature, the volume resistivity r is not less than 1012 W.cm; the insulation resistance constant Ki is not less than 36.7 MW.km.

4, technical parameters:

1) The finished cable is subjected to 3500V AC frequency voltage test for 5 minutes without breakdown;

2) The heat resistance, cold resistance, chemical resistance, insulation resistance and service life of cross-linked polyethylene insulated control cables are far superior to those of PVC insulated control cables.
