DPC-4 Series VCB Hand-operated Chassis
1.Circuit breaker components, it can match with VSI, VBI,VSG etc.
2.Used in the swithgear, vacuum circuit breaker.
3.The pole distance is 275mm, and it is matched with the swith cabinet with the width of 1000mm.
4.It is Assembled with the lock plate completly.
DJ-DD02A Series of VCB Motorized Chassis
1. Good generality. The overall and installation dimensions are same as that of common manual chassis.
2. Using high-precision ball screw rod to replace original aluminum screw rod, which make chassis is stable as moving in and out, and nearly no clearance during transmission. The ball screw rod has small movement resistance, high accuracy and high bearing capacity. It solves the problem that when pushing VCB of high current into a switchgear, the chassis may be distort due to low intensity of screw rod.
3. Using modular integral gear motor to replace original chain transmission, which makes motor driving torque increased, so that solves problem of chain loosened or fractured.
4. Motorized and manual operation adopts two independent systems during working. It means that screw nut works as motorized operation and screw rod works as manual operation. It will not happened that personal injury caused by manual misoperation during motorized operation. It needn’t to switch between manual and motorized operation, can be operated directly.
5. No matter under normal condition or locked rotor happens during motorized operation, chassis can be operated by manual conveniently. The following conditions will not happen: chain of motorized chassis is fracture or loose; as switching between manual and motorized operation, the clutch doesn’t trip; chassis can not be operated as its motorized transmission part is damaged or stuck.

11kV 12kV 33kV Embedded Pole For VCB
1.Epoxy embedded poles, or called embedded vacuum interrupters, vacuum interrupters with epoxy resin, is made by casting vacuum interrupters, main circuit conduct and mounting parts with epoxy into an integral part.
2.The main advantages of this technology (compared to an assembled or open pole system) are its high dielectric strength as well as better protection against environmental influences.
3.Embed the vacuum interrupter in resin make the pole particularly sturdy and protect the interrupter from impacts, dust deposits and humidity. The design is compact, robust and modular.
4.Another important advantage is the fast and easy assembly of the pretested and adjusted poles on the vacuum circuit breakers.
