The construction and materials withstand harsh conditions to ensure running with reduced spark noise.
In order to achieve high voltage resistance, resistors are built in using a thermal pressure input. It also has a long design of the resistance body to stabilize the resistance.
Adopts a stable ceramic resistor value. Longer resistors prevent flashover and provide excellent noise suppression
The terminal seal and waterproof cap are made with special waterproof shape and high quality synthetic rubber for superior waterproofing.
The construction uses phenolic resin with excellent mechanical strength, heat resistance and voltage resistance.
