In urban power grid reconstruction projects, cables, especially polyethylene insulated power cables, have been widely used. However, due to the particularity of the cable, there are special requirements for the installation, operation and maintenance of the cable. Cable dampness or water ingress reduces the insulation resistance of the cable, it is a few important aspects that cause the operation accident of cable line. See More Consultation Project

Relative immunity to short circuits caused by external forces (wind, fallen branches), unless they abrade the insulation.
Can stand in close proximity to trees/buildings and will not generate sparks if touched.
Little to no tree trimming necessary
Simpler installation, as crossbars and insulators are not required.
Ease of erection and stringing, less labor intensive, less construction resources needed.
More aesthetically appealing.
Can be installed ...
First, Scorch phenomenon of PVC cable material when extrusion
Mold export smoke, the smell of strong stimulation and crackling; plastic surface with particles of burnt material; together there is a continuous bubble.
1. Screw long-term use, the screw is not cleaned, accumulated scorched material out; split screw cleaning can be completely.
2. Heating time is too long, plastic aging, scorch; shorten the heating time, check the heating system is a problem, and timely maintenance.
The Relationship between Sheath Thickness and Cable Quality
Sheath thickness below the standard requirements of course is unqualified, but the thickness exceeds the standard requirements, but also unqualified. For example: cable model ZR-KVVP 4 * 2.5mm2, measured thickness of the sheath thickness of 1.6mm, this model as reference to GB9330-88 standard requirements, the thickness should be 1.2mm. The reasons for their failure are the following:
