What do you need to pay attention to during the installation process of wire and cable?

In the construction of power cables, steel brackets are used, steel protection tubes are used, and cable cards and overhead cables are used. Any galvanic (iron) closed loop is formed around the power cable, and eddy currents may form. Especially in high current power cable systems, eddy currents are greater. Construction of power cables...

Engaged in the wire and cable industry must pass the basic knowledge of the cable, the general cable companies in the recruitment of no basic staff will be trained, the following for you to organize the basic wire and cable training knowledge, hope to help you!

Wire and cable encyclopedia basic knowledge points, wire and cable products of thousands of types, applied in all walks of life. Their general use has two kinds, one is to transmit the electric current, one is to transmit the signal. The most important control technical performance index of the transmission current type cable is the conductor resistance and pressure resistance performance; the technical performance of the transmission cable is mainly controlled by...

Wire and cable expertise - basic knowledge of rubber-insulated wire and cable, wire and cable refer to materials used for power, communications and related transmission purposes. "Wire" and "cable" do not have strict boundaries. Usually, a product with a small number of cores, a small product diameter, and a simple structure is called a wire, and a wire without an insulation is called a bare wire. Others are called cables.

The main insulation and sheath material of plastic wire and cable is plastic. Thermoplastics are superior in performance and have good processing performance, especially when used in the extrusion of insulating layers and sheaths for wires and cables. The basic method for the production of plastic insulation and sheathing of wire and cable is the continuous extrusion of a single screw extruder.

It is widely used in power cable engineering, power transmission and transformation projects, communications and optical cable line engineering, cross-sea and river-crossing cable protection projects, aviation airports, traffic roads and bridges, industrial park cable engineering, municipal construction underground cable engineering; it can also be used Civil and industrial water distribution, sewage discharge and other projects.

Wire and cable are used to transmit electrical (magnetic) energy, information, and wire products that convert electromagnetic energy. The generalized wire and cable is also referred to as the cable. The narrower cable is the insulated cable.

The industry has always been arguing about the characteristics of the network data cable sheath, such as whether the skin can meet the flame-retardant or low-smoke standard, whether it needs to have a high ignition point, fire resistance, but it will release toxic gases in the fire. halogen?

In the integrated wiring from the large categories to distinguish the two kinds of wiring way wrong wiring and shield the wiring two categories, shielding wiring way first originated in Europe, the main outside the common unshielded cabling system combined with metal shielding layer, the principle is to use metal shielding layer of emission, absorption, and skin effect to realize the function of preventing electromagnetic interference and electromagnetic radiation, the principle of comprehensive utilization of the twisted-pair cable shielding system balance and shielding layer shielding effect

1. Rated voltage of wire and cable products (u0/u): 300/500v2, long-term working temperature of wire and cable is 70 °C3, the ambient temperature when layin...

A cable is usually a rope-like cable made by twisting several or several sets of wires (at least two in each group). Each set of wires is insulated from each other and often twists around a center. The entire bread has a height.

One, scorch1, the phenomenon of scorching(1) The temperature reflects ultra-high, or the temperature of the control of the instrument fails, causing the plastic...

Wire and cable performance refers to what kind of knowledge, wire and cable products are used in different occasions,

Flame retardant fireproof wire and cable technical parameters, fire-resistant flame retardant cable, can keep the integrity of the circuit in case of fire, and ensure the function of critical emergency system is safe and normal.At present, there are a large number of fire alarm systems, smoke detection systems and emergency... in large shopping malls, hospitals, offices, stations, airports and residential buildings.

Then the wire and cable in the end to do what test? What standard? First, the wire and cable... Mainly used for a variety of motors, instrumentation, etc. Second, what needs to do test certification?
