Detachable lightning arrester
Short Description:
Surge arrester is an overvoltage limiter that protects transmission and transformation equipment (transformers, switches, capacitors, wave blockers, transformers, generators and motors, power cables, etc.) from overvoltage damage. It is the foundation of insulation coordination in power systems.
Product details
Surge arrester is an overvoltage limiter that protects transmission and transformation equipment (transformers, switches, capacitors, wave blockers, transformers, generators and motors, power cables, etc.) from overvoltage damage. It is the foundation of insulation coordination in power systems.
The main component of the metal oxide lightning arrester, the metal oxide resistor, is manufactured by our company using foreign technology through optimization and improvement. It has excellent nonlinear (volt ampere characteristics), good steep wave response, strong current carrying capacity, and excellent aging resistance, greatly improving the protection capability and reliability of the lightning arrester.
The metal oxide lightning arrester with composite sheath adopts the overall injection molding and two end encapsulation process, with good sealing performance, excellent explosion-proof performance, anti pollution, anti electric insects, anti-aging, small size, light weight, and easy installation and maintenance.
Ceramic coated metal oxide lightning arrester has good structural characteristics, durable sealing properties, relatively uniform potential distribution, and reliable pressure release device.
Environmental conditions for use:
The ambient temperature should not exceed+40 ℃ and should not be lower than -40 ℃
◆ Solar radiation:
Note: The maximum solar radiation (1.1kW/m2) has been considered through preheating the test sample in the type test. If there are other heat sources near the lightning arrester, the use of the lightning arrester needs to be negotiated between the supply and demand parties.
◆ Altitude not exceeding 1000m;
The frequency of the power supply shall not be less than 48Hz and shall not exceed 62Hz;
The power frequency voltage applied between the terminals of the lightning arrester for a long time should not exceed the continuous operating voltage of the lightning arrester;
Areas with earthquake intensity of 7 degrees or below;
The upper limit wind speed shall not exceed 35m/s.
