It mainly includes a lighting distribution box for controlling the lighting system and a power box for controlling the power system. Most of these products are combined, and can control up to 12 circuits. Most of the shells are made of cast aluminum alloy materials, and some of them are welded by steel plates. A small part of Xi'an explosion-proof electrical appliances is of insulating material . Its interior is mainly composed of circuit breakers, contactors, thermal relays, transfer switches, signal lights, buttons and other components. The manufacturer can also choose to be equipped according to user needs.
Explosion-proof grade. It can reach ⅡCT6 grade. By the way, explosion-proof automatic switches, explosion-proof knife switches, and fuses are also often used in some control applications to control the power or the lighting of the power distribution system. They just become a single piece. Therefore, these products are also classified in this category.
Second, explosion-proof starters
Such products include manual starters, electromagnetic starters, reversible electromagnetic starters, autocoupling reduced pressure starters, Y-transformer step-down starters and feed switches.
Explosion-proof starter products are used as terminal control equipment. Generally, one starter controls one motor. Xi'an explosion-proof electrical appliances belong to a wide range of products. Its casing is usually made of cast aluminum alloy or steel plate. Its interior is generally composed of contactors (air or vacuum), motor protection systems, signal lights, buttons and autotransformers, etc., and generally has local control, remote control and automatic control functions. Some products are equipped with a circuit breaker as the main switch to make the product more complete.
Third, explosion-proof control switches
The market demand for this type of product is also relatively large. Therefore, there are many manufacturers of Xi'an explosion-proof electrical appliances , which mainly include small explosion-proof products such as lighting switches, transfer switches (combination switches), travel switches, and wire switches. The explosion-proof grades of these products can reach ⅡCT6 level. The explosion-proof shells and shells are usually composite structures made of die-cast aluminum alloy. There are also a few manufacturers using other materials.
These products are characterized by small size, single internal components, low technical content, simple structure and easy fabrication.
