供应JFEYH10KV高压电机引接线生产厂,供应JFEYH10KV高压电机引接线生产厂,JFEYH10KV高压电机引接线江苏春晨电缆有限公司生产，The difference between wire and cable has no strict boundaries, but in a broad sense, the cable structure is complex, it has complex wire sheath, and has the advantages of simple structure and some only a conductor and an insulating layer, some only woven waxing protective layer coated with a layer of light or light soft protective layer. The conductive core wire the cable is used to transmit current. In order to reduce the power loss and voltage drop, the conductive wire core generally made of copper and aluminum high conductivity. The insulating layer prevents the leakage current along the radial direction, to ensure safety. So the insulation layer should have good dielectric properties and heat resistance of certain. The mechanical strength of.JFEYH10KV high voltage motor lead wire

In the protection of insulated wire or cable core into the outside covering layer called shield cable (in the protection sheath outside of the covering layer is called the outer layer). The main effect of the protective layer is the protective insulating layer. Its main performance is moisture-proof, anti oil, anti aging, corrosion resistant fluorescent. Well, mechanical protection (outer protective layer of the main role is to strengthen the mechanical protection. On cable tension, it also has anti bump), electricity, magnetic dry effect, JFEYH10KV high voltage motor lead wire

From the perspective of wire and cable sheath, braided wire and cable sheath or many kinds of external protective layer. However, according to the material and woven wire cable braid layer used in wire and cable structure in different parts, the braid effect is obviously different.

First, the role of fiber woven layer JFEYH10KV high-voltage motor wiring

For wire, woven fiber layer is the protective layer of a light form. Its main role is to protect the insulation or less are not subject to a variety of light, heat and moisture. Low temperature, acid gas erosion and other external mechanical damage, and ensure the safe operation of power lines. As for cable, fiber woven layer often is in the middle of the protective layer, so as to enhance the tearing strength of the protective layer, such as reinforced rubber or plastic protective sheath is in the middle layer with cotton, hemp fiber woven layer, in order to improve the strength of the protective layer.

Two, the role of metal braid

The metal layer is mainly braided copper wire braided layer and steel wire (wire) braided layer two,

The main function of copper wire braid is:

Such as the Blue Shield tinned copper wire braided copper wire braided cable, control cables of l- electromagnetic interference.

2 eliminate the shielding effect of the surface potential of the power cable, which is bound to the power line and to eliminate the induced current, such as the total shielding of the high-voltage cable

The shielding effect of 3 security protection. In the main braided copper core insulation wire core and with good contact or for energy leakage timely response, such as shielding cable for mine

The main role of wire braid:

L. mechanical protection. Such as shipboard power cable type CF31

2 under longitudinal tensile force, such as marine geological exploration by WC- GC, WCT magnetic measuring cable type.

3 magnetic shielding.
