China Indoor HV Safety Disconnect Switch Manufacturer, Supplier, Factory

SanGao high quality Zinc oxide lightning arrester It is a voltage and current protector with functions such as overcurrent, overvoltage, and undervoltage protection. When the current/voltage deviates from the set value, the relay automatically cuts off the power supply to prevent fire and protect electrical equipment. It also has an automatic reset function, which means that when the voltage and current return to normal values, the power supply will automatically recover.

SanGao high quality High Voltage earthing Switch is also called earthing switch. Earthing switch and earthing switch are used interchangeably. It is a protective device included in switchgear components such as circuit breakers and isolators. When the circuit breaker is removed and shaken out, the earthing switch automatically grounds the busbar section close to the circuit breaker. For isolators, the earthing switch contacts the busbar when the isolator isolates the circuit, releasing any charge that may have accumulated there.

SanGao, a China company has launched the Indoor Grounding Switch, an advanced high performance product designed to meet the highest technical standards. This grounding switch has undergone rigorous evaluation and complies with GB1985 and IEC62271 standards, and is suitable for 3-12kV, three-phase AC 50Hz power systems. Every distribution system must be equipped with protective devices to protect electrical appliances and equipment from the impact of accidents. It has short circuit closing capability, which can protect other electrical equipment from potential damage, and can be seamlessly integrated with various medium voltage switchgear. In addition, it is also a key protective component in the maintenance process of medium voltage electrical equipment.

SanGao high quality HV Vacuum Load Break Switch, As independent components, they are offered at highly competitive prices. We offer two types of switches: the ultra-high speed model HVS-XXX-F, which can vary voltage within ± 15% of the rated value; And switch model HVS-XXX-V with a wide range of applied voltage.

SanGao high quality Load Breaking Switch, a load switch, also known as a load switch, is an electrical switchgear used in power systems to disconnect and connect load currents. It is mainly used in medium voltage distribution systems (typically 3.6kV~40.5kV). Load switches usually have a certain ability to interrupt load current, but cannot interrupt short-circuit current. They are usually used in conjunction with protective devices such as fuses or vacuum circuit breakers.

SanGao advanced Cut out Fuse is equipped with standard fuse links, which can protect transformers, capacitors, cables or lines from short circuits and overloads in 11KV~38KV overhead distribution systems. If a short circuit occurs, the molten metal strip will melt, protecting electronic devices from overcurrent damage and internal electronic component operation errors. Fuses are widely used in power systems, electrical equipment, and household appliances. What's that? Fireworks in October? It's unlikely... more precisely, the bright blue flash you see on stormy and rainy nights is likely a fuse that protects the power grid.
