China IEC 61439 certified switchgear power transfer assembly Manufacturer, Supplier, Factory

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.

The switchgear ground knife controller is a vital device used in electrical systems to operate ground knife switches, which are essential for safely grounding equipment during maintenance and servicing. This controller provides reliable and precise control over the opening and closing of ground knife switches, ensuring effective isolation and protection of electrical circuits.

GN19-12(C) indoor HV disconnect switch applies to power system of rated voltage 12kV, AC 50/60Hz. It is equipped with CS6-1 manual-operating mechanism and is used to break and make circuit under no-load. There are additional pollution type, high-altitude type and power indicating type. It is made as per IEC 62271-102. The isolating switch of this series is equipped with a CS6-1 manual operating mechanism (the isolating switch with a panel has its own conjoined operating mechanism).   This series of isolating switches is a three-pole type, which consists of a chassis, a rotating shaft, a lever, a porcelain pillar insulator, a knife and a wiring board. The rotating shaft is arranged on the bottom frame, on which three pairs of levers are welded, and the levers pass through the pull rod porcelain insulator and the knife necklace. The rotating shaft extends out of the base frame, and any section of the rotating shaft can be connected with the operating mechanism.   Type C is through the wall. Among them, C1 means that the rotation is on the side through the wall; C2 means that the disconnection is on the side through the wall; C3 means that both sides are on the side through the wall.

Micro Switch for Switchgear are critical components in electrical switchgear systems, designed to support and isolate high-voltage conductors while ensuring operational safety and efficiency. These insulators are typically made from high-quality materials such as porcelain or polymer, offering excellent dielectric properties and mechanical strength. Their robust design allows them to withstand extreme environmental conditions, including temperature fluctuations, humidity, and pollution, making them suitable for both indoor and outdoor applications.

Sulphur hexafluoride (SF6) is a good gas insulator. Its typical application is gas insulation in high-voltage switchgear of power supply systems. When the sulphur hexafluoride gas encounters high heat and high temperatures(e.g. arc), it produces hydrogen fluoride and sulphur dioxide gases, which coexist with undecomposed sulphur hexafluoride gases. The rated pressure of the SF6 high voltage circuit breaker is usually 0. 0.6 MPa(table pressure). The pressure of the SF6 gas must be checked against the temperature curve of the product when inflating or checking the temperature curve. FLN36-12kV SF6 load break switch is a switch equipment for medium voltage switchgear, using SF6 gas as arc extinguishing and insulating medium. There are three working positions: open, closed, earth position in the switch. The compact size, easy installation, and fine adaptability to environment make the switch suitable for many different applications.
