OVERVIEW OF THE GUTIERGEAR
Gutiergear cabinet is made by high strength galvanized steel plate and high strength hardware. The cabinet with integral design has high mechanical
strength, precision and resistance to corrosion and oxidation with nice appearance. The meter chamber and cabinet body are in whole assembly structure. The switchgear can be removed out without dismantling the secondary connection in replacement, which reduces much workload of mainte-nance. Door panel of breaker chamber is in the pattern of fixed setting. The secondary cable channel is on both sides of front switchgear.
