Electrical Wire

Cable overhead steel strand

In order to protect the outer sheath of the cable from harm and reduce friction, the cable pulley is suspended on the steel strand. Its spacing is related to the weight of the cable unit length, generally installed every 2~3m distance, in order not to make the cable sag touch the ground as the principle, the cable pulley into a straight line installation. The wire mesh sheath is set at the end of the cable when used. When pulling the cable, the cable mesh sleeve and the wire rope must be installed between the anti-twist device.

AC winding

The potential and magnetic potential generated by the AC winding and the final electromagnetic performance are only related to the connected conductors, but not to the order of connection. In other words, as long as the conductors are connected in the same slot, it does not matter which one is connected first and which one is connected second, the final reflected electromagnetic performance is basically the same, only the ends are different, there may be slightly different end leakage resistance and DC resistance.

yjv cable insulation material

According to the cable laying environment and the different load, is designed to choose the cable specification type specifications. The non-armor type is suitable for overhead, indoor, tunnel, cable trench, etc. It cannot bear the action of J mechanical external force, while the armor type can be buried underground under the same conditions as the non-armor type. Can withstand certain mechanical external force. Single-core cables are not allowed to be laid in pipes that produce magnetism. Flammable and explosive, chemically corrosive and high temperature, low temperature and other occasions should choose a special type of cable.

How to choose waterproof cable material

Cable waterproof way is generally divided into two kinds of longitudinal water resistance and radial diameter water. Longitudinal water resistance is generally used to block water yarn, water-blocking powder and water-blocking tape, their water-blocking mechanism is in these materials contain a water-expandable material, when the water from the end of the cable or from the sheath defects into the water, this material will be water quickly expand to prevent further diffusion of water along the cable longitudinal, so that the purpose of the cable longitudinal waterproofing. Radial water resistance is mainly achieved by extruding HDPE non-metallic sheathing or hot pressing, welding, cold drawing metal sheathing.

The difference between high voltage and low voltage cables

The difference between high-voltage cables and low-voltage cables lies mainly in the rated voltage withstood and the difference in the environment and use. Therefore, when selecting and using cables, it is necessary to determine the appropriate cable type according to the specific application requirements and standard regulations.
