Product introduction of low-voltage switchgear:

 

Low-voltage switchgear is a kind of power distribution equipment used in low-voltage power systems, usually consisting of electrical components, control components, enclosures, circuit breakers, etc., for controlling, distributing and protecting circuits. It has the characteristics of compact structure, convenient operation, safety and reliability, high degree of intelligence, and is widely used in various industrial, commercial and civil buildings in the power system. Common low-voltage switchgear include distribution cabinet, control cabinet, compensation cabinet, frequency conversion cabinet, etc.
