2. Product features
a. Four-star connection method can greatly reduce the phase-to-phase overvoltage. Compared with the conventional lightning arrester, the phase-to-phase overvoltage is reduced by 60-70%, and the reliability of protection is greatly improved.
b. The structure of the zinc oxide nonlinear resistance and the discharge gap are connected in series to protect each other.
c. The voltage impact coefficient is 1. The discharge voltage values are equal under various voltage waveforms, and are not affected by various overvoltage waveforms. The overvoltage protection value is accurate and the protection performance is excellent.
d. The instantaneous value of discharge is similar to the residual voltage after the action, and there is no chopping, which is more conducive to the protection of the inter-turn insulation of the equipment.
It adopts silicone rubber outer casing and high-voltage cable outer lead structure, which has the advantages of easy installation, strong sealing, small volume, shock resistance (vibration) and so on.
- Long protection distance
- High energy input capacity
