Surge Protector
Surge Absorber
Features
◆ Uses silicone, a newly arising novelty polymer material
◆ Excellent pressure relief and airtight structure
◆ Suitable for outdoor and damaged areas
◆ Unchanging surge absorption abilities in long-term uses
This is a protective equipment used in AC power circuit to protect power apparatus and system circuit from switching surge that may occur in making and breaking a circuit due to earth fault, VCB, no load MOLD transformer, low-capacity MOTOR.
- The product has a FRP filament winding structure, which leads to excellent pressure relief. This makes the product safe from explosive accidents.
- It is light and small which makes transport and stroage easy.
- The product is completely airtight.
- Its housing is made up of silicone, which makes it suitable for use in damaged areas or outdoors.
- It uses silicone, which is an excellent water repellent. This makes it suitable for use in damaged areas or outdoors.
- The product uses zinc oxide which has an excellent ability to withstand current impulse. This means that it retains its perfect surge absorptive abilities despite long-term use.
