33KV 36KV 40.5KV, 3-phase, AC 50/60Hz
Standards ISO IEC GB

Product Introduction

◆ The cabinet structure adopts the assembled type, and the circuit breaker adopts the handcart floor type structure;

◆ Equipped with a new type of composite insulated vacuum circuit breaker, and has the characteristics of good interchangeability and easy replacement;

◆ A screw nut pushing mechanism is installed in the handcart frame, which can easily move the handcart and prevent misoperation from damaging the propulsion structure;

◆ All operations can be performed with the cabinet door closed,

◆ The interlocking between the main switch and the door of the handcart switch cabinet adopts the mandatory mechanism locking method to meet the "five prevention" function;

◆ There is ample space in the cable room and multiple cables can be connected;

◆ Fast grounding switch is used for grounding and loop short circuit;

◆ The enclosure protection grade is IP3×, when the handcart room door is open, the protection grade is IP2×;

◆ The product conforms to GB3906, Dl404 and adopts the international IEC298 standard by reference.
