When there is a wire breakage inside the cable or cable, the exact position of the wire break is difficult to determine due to the wrapping of the outer insulation skin. This problem can be easily solved with a digital multimeter.

电线电缆是根据基本测量单位的长度，所有电线电缆从导体加工开始，在导体外围逐层加隔绝，屏蔽，布线，护套等制成电线和电缆产品。产品结构越复杂，堆叠的层越多。电线电缆生产过程1....

First, the cable concept[electric cable; power cable] is usually a cable-like cable made up of several or several sets of wires [at least two in each group], e...

The vigorous development of urbanization has made urban space more and more tense. Because of the demand of industrial enterprises, cable entry has become an inevitable choice. However, in recent years, external insulation damage and installation quality have caused cable insulation breakdown and even explosion, which have become major accidents in the power grid. In general, there are several reasons for cable insulation breakdown.

Why should a return line installed along the cable be installed in the grounding mode of the single-core cable sheath at one end?Can a cable project be divided into several projects?...

Low-smoke, halogen-free cable refers to an environmentally friendly cable that is made of a rubber material that does not contain halogens (F, Cl, Br, I, At), and does not contain lead, cadmium, chrome, mercury, etc., and does not emit toxic fumes when burned. The following is the evolution and rise of low-smoke halogen-free flame retardant cable materials organized by cable recruitment network. Welcome to know!

The technical specifications for wire and cable pipe and wire slot can help friends fully understand the importance of electrical installation.

Copper core cables have more advantages than aluminum core cables: 1. Low resistivity: The electrical resistivity of the aluminum core cable is about 1.68 times higher than that of the copper core cable. 2. Good ductility: The elong

Copper is the main conductor material used in wire and cable products, so the copper core code is written in T, except for bare wires and bare conductor products. Bare wire and bare conductor products, power cables, and electromagnetic wire products do not indicate large class codes. Wires and cables for electrical equipment and communication cables are not listed, but subcategories or series codes are listed.

With the deepening of the implementation process of distribution automation, it is necessary to enter the advanced stage of distribution automation, and to carry out computer intelligent management of the whole process of dispatching, production, operation and maintenance of the distribution network,
