A sensor is a detection device that can feel the information being measured, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule, so as to satisfy the transmission, processing, storage, and display of informati...

Insulator is a special insulation control device which can play an important role in overhead transmission lines. In the early years, insulators were mostly used for telegraph poles, and later they gradually developed into the high-voltage wire connecting tower with a lot of disk-shaped insulator...

Cable terminal heads and intermediate joints are important components in power transmission and transformation cable lines. Their function is to disperse the electric field at the cut-off part of the outer shield of the cable terminal head, protect the cable from breakdown, and have internal and ...

The cable plug head mainly includes three parts: branch gloves, semi-conductive tube (stress tube), and insulating sleeve; the elbow joints seen in switch stations and box transformers are actually equivalent to insulating sleeves. Of course, equipment manufacturers will Equipped with a semi-cond...

When the high-voltage cable branch box heats up, it is controlled according to certain methods and methods to ensure that it will not be affected to a certain extent in the actual treatment, and affect the operation and value in actual use; first, perform temperature monitoring, according to the ...

What is the difference between the front connector and the rear connector of the Deadbreak connector! Generally speaking, under normal circumstances, a set of front connector are needed to enter a three-core high-voltage cable in a ring main unit. If it is connected through a wall bushing,after i...

The function of the surge arrester is to protect various electrical equipment in the power system from damage caused by lightning overvoltage, operating overvoltage, and power frequency transient overvoltage. The main types of lightning arresters are protective gaps, valve arresters and zinc oxid...

There are many forms of cable connectors, and different forms have their own characteristics. Among them, the Deadbreak cable connectors are fully insulated and fully sealed terminal cable heads that can be touched with electricity; they are widely used in outdoor distribution transformers, box t...

The cable branch box must meet the requirements of convenient installation, and the incoming and outgoing wires must be flexible enough to facilitate installation; in general, the cable branch box should have 6 to 8 branch inlets and outlets, so that it can be used. Meet the circuit transmission ...

What is a cable fault indicator? Fault indicator is a kind of electromagnetic induction equipment that can reflect that there is a short circuit current through the fault sign (red card). Install the fault indicator along the distribution line. Once the line fails and the short-circuit current fl...

The fully insulated SF6 ring network cabinet is composed of load switches, load switch-fuse combination electrical appliances, isolation switches-circuit breakers and other main switches to form functional units and sealed air boxes. It will all high-voltage live parts such as load switches, bus-...

Measurement method of cable joint: 1.Temperature sensing cable type temperature measurement. Place the temperature sensing cable in parallel with the cable. When the temperature of the cable exceeds a fixed temperature value, the sensing cable is short-circuited and an alarm signal is sent to the...
