Plastic local telephone cable construction

1 , Conductor: conductive core nominal diameter of soft copper 0.32,0.4,0.5,0.6,0.7,0.8,0.9 mm .
2, using solid core polyolefin or foam polyolefin or polyolefin insulation foam solid leather as insulation.
3 pairs : the a, b two different colors of insulated cores twisted as a pair.
4, the cable core structure: twisted wire pairs 12, 13 sub- units of 25 basic units , 50 pairs, 100 pairs and 200 pairs of super- units. Flag ribbon around the outside unit sparse . Cable core usually consists of one or more units.
5 , the filler (only filled cables ) ; cable core gap filling water blocking compound.
6 , comprehensive protection layer : the core layer of outer longitudinal package for double-sided plastic composite aluminum shield , and in its outer layer of black extruded low-density polyethylene , a common form of tidal jacket layer .
7 , self-supporting cable: 8- shaped extrusion die , for self-supporting cable and aluminum cable core longitudinally extruded simultaneously .
8 , armor (for armored cables 23,22,53 type ) ; outside the integrated sheath wrapping two galvanized steel (for 23, 22 cable ) or longitudinally layer coated steel ( applicable at 53 cable ) .
9, the outer sheath (for armored cables 23,22,53 type ) : On the armor layer extruded polyethylene or polyvinyl chloride.
10 , may provide protection against rodents , termite resistance, chemical resistance and flame retardant cable and other functions based on user requirements .
