China Indoor High Voltage Earthing Switch Manufacturer, Supplier, Factory

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.

You can wholesale SanGao AC Isolation Switch, It is completely powered off during daily maintenance and upkeep, and quickly shut down in emergency situations. This switch isolates the circuit from the main power supply and releases any residual current in the circuit, ensuring safe operation and quick shutdown and cutting off of any current when an emergency stop is required.

SanGao focuses on the research and development of High Voltage Isolation Switch. Our security sensors can reduce costs, improve efficiency, save energy, and promote environmental sustainability. In addition, the grounding switch is used in conjunction with the isolation switch to provide effective grounding/connection, grounding the power-off part of the system. We provide customized professional technical support.

SanGao's HV Indoor Vacuum Circuit Breaker is a key protection and control device in the power system, mainly installed in indoor environments. Under dispatch instructions, it safely closes (connects) or opens (disconnects) high-voltage circuits to operate equipment.

SanGao High Quality High Voltage Circuit Breaker is an outdoor distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current, and short-circuit current in power systems. It is suitable for distribution control in substations, industrial and mining enterprises, and urban and rural power grids, especially for frequent operation scenarios. This product complies with GB1984-2003, DL/T 402-2007, and IEC60056 technical standards, and supports remote monitoring and automation control.SanGao has gradually become a high quality supplier in China's High Voltage Circuit Breaker industry. They are widely used in urban and rural power grid renovation, transmission and distribution engineering, sewage treatment, hydropower stations, wind power plants, metallurgical industry, petrochemical industry, mining, railways, residential area construction, and power engineering projects. Normal operating environment ◆ Surrounding air temperature: -30 ℃~+60 ℃; ◆ Altitude: not exceeding 3000m; The wind speed does not exceed 34m/s; Vibration or ground motion from outside the switchgear and control equipment can be ignored; Pollution level: Level IV; Storage temperature: -40 ℃~+85 ℃. Characteristics of switch structure 1. The High Voltage Circuit Breaker features a three phase pillar structure that is maintenance free, small in size, lightweight, and has a long lifespan. 2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture proof and anti condensation performance, especially suitable for use in cold or humid areas. 3. The three-phase pillars and current transformers adopt imported outdoor epoxy resin solid insulation, or indoor epoxy resin wrapped with organic silicon rubber solid insulation; It has the characteristics of high and low temperature resistance, UV resistance, and aging resistance.

Drop-Out Fuse is manufactured and supplied by SanGao for use in overhead distribution systems, including fuses, fuses, and accessories. Drop out fuse is an electrical safety device used for utility poles to protect electrical equipment and systems from overload or short circuit damage. Drop out fuse, also known as drop out circuit breaker or simply circuit breaker, is an electrical fuse mainly used in distribution lines to protect transformers, wires, and other equipment from overcurrent effects.
