The working principle and structure of the load-break switch itself are relatively simple, but due to a large amount of use and high working reliability requirements, it has a greater impact on the design, establishment, and safe operation of substations and power plants. The main feature of the load-break switch is that it has no arc extinguishing capability and can only open and close the circuit when there is no load current. So how to improve the error prevention of the load-break switch? Next, let's go take a look.

Fuse cutout refers to an electrical appliance that fuses the melt with the heat generated by itself when the current exceeds the specified value. Fuse cutout is based on the current exceeding the specified value for some time, the melt is melted by its heat, thereby breaking the circuit; a current p

The fuse cutout switch combines the traditional fuse and switches into one fuse combination electrical appliance. The fuse cutout switch not only can be operated with a load but also has obvious current limiting characteristics and good selection characteristics, which can realize the best protection of the line and can be widely used in low-voltage power distribution systems. Next, let's take a look at the introduction of the fuse cutout switch. Here are some answers.

Load break fuse cutout is widely used as a protection device in electrical equipment and household appliances because of its simple structure and easy use. So what is the difference between a load break fuse cutout and a circuit breaker? Next, let's take a look at the difference between load break f

The protective property of polymer-type fuse cutout is also called melting property. When the current exceeds the specified value, it uses the heat generated by itself to fuse the melt and break the circuit. The function of polymer type fuse cutout in the circuit is over-current protection, which can also be called short-circuit protection. Next, let's take a look at the operation precautions and operation and maintenance of polymer-type fuse cutout. Here are some answers.

A cold-shrinkable tube generally refers to tubular cable accessories using cold-shrinking technology, which has the functions of insulation, sealing, and protection. At present, cold shrinkable tubing is divided into Silicon Rubber cold Shrinkable Sleeve and EPDM cold shrinkable tubing according to the main raw materials for manufacturing. They are made of silicone rubber and EPDM respectively. Next, let's take a look at the introduction of Silicon Rubber cold Shrinkable Sleeve. Here are some answers.
