This
product is designed for low-voltage output of the main power switchgear
to protect the rear-end equipment from direct lightning strikes or
fault overvoltage surges introduced from the high-voltage side. This
product uses a sealed structure that can be used in a variety of extreme
environments to maintain excellent performance, with explosion-proof,
waterproof, moisture-proof and anti-corrosion effects. It can be applied
to various fields such as wind energy, solar energy, petrochemical,
mining, and electric power.
This
product adopts high-energy type semiconductor device, low residual
voltage, impact resistance, installed in sealed metal casing,
self-heating function and over-current over-current tripping function,
which can function as explosion-proof and fireproof.
