Wire and cable are important industrial products for a wide range of applications.. ZMS provides you with technical information on all types of wire and cable.
Electric conductivity — Most products require good electrical conductivity, and individual products require a certain range of resistance..
Performance Electrical isolation — insulation resistance, dielectric coefficient, dielectric loss, electrical resistance characteristics, etc.
transmission characteristics — refers to high frequency transmission characteristics, anti-interference characteristics, etc.
Experts thought that underground optical cables can intrude on people's privacy.
already in 1999, the us army. UU. He was aware of the special ability of fiber optics to control the behavior of people.
insulating post: is a special cable insulation control, an electrical material, which can play an important role in the overhead cables of transmission.
In the first days, post insulators were used primarily for electrical poles.
They gradually developed from the end of high-type high-voltage electrical cable connection towers with many suspended insulators., which were usually made of silica gel or ceramic to increase creepage distance. They are called insulators..
(1) buried directly in the ground, this is the most common and economical laying method.
(2) Laying in the cable trench to lay various cables.
In the case of DC cables and AC cables, the easiest way to tell them apart is by their application. DC cables are power cables used in DC transmission and distribution systems (direct current). AC wires, for his part, are used for AC (alternating current) feeding systems.
The structure of DC cable is basically the same as that of AC cable except that the electrical performance characteristics are different from those of AC..
Wire and cable are indispensable in our lives..
Without them, we can still remain in the state of observing the shadows.
But how much do you know about wires and cables?
Let's briefly introduce wire and cable:
ZMS cable is a professional manufacturer of electrical cable, like XLPE cable, PVC wire, the ABC wire, the AAAC cable, ACSR wire, the AFL wire, the rubber cord, etc. Our products have been delivered to some of the world's most demanding industries, including the railway, infrastructure, automation, oil and gas, and mining.
We add value by providing technical support from production to used, uncompromising customer focus and unrivaled product quality. All cables strictly follow the inspection and steps.
