Wire and cable sheath thickness and cable quality

In the purchase of wire and cable, wire and cable sheathing is also one of the factors to be considered, then the thickness of the wire and cable sheath and cable quality What is the relationship? Next, on this issue, give you a brief introduction:

Wire and cable sheath thickness, the quality of wire and cable common impact has the following two aspects:

1, directly to the normal use of wire and cable products for a long time.

Wire and cable in normal applications, often buried, immersed in water or exposed to easily corroded environment. Prolonged or subject to external corrosion, so that the quality of the sheath will be punctured so that the protective effect of the cable jacket will be lost.

2, increase the difficulty of laying wire and cable

More and more environmental requirements of high-voltage cable products must be small outside diameter, in the process of laying need to consider leaving gaps in order to dissipate the heat generated by the wire and cable power, the sheath thickness is too thick will increase the difficulty of laying , So the thickness of the sheath in strict accordance with the relevant standards, or cannot play a role in protecting wire and cable. Can not blindly pursue its thickness.

Wire and cable sheath unqualified common causes are:

Material performance defects. Material performance is not reflected through the thickness.

There is a problem with the cable structure. If the conductor, insulation, weaving density.
