Product Desciption
General:
VD4 medium-voltage indoor vacuum circuit breaker is applicable for three-phase AC power system of rated voltage up to 7.2kV~24kV and frequency 50/60HZ,widely used in many fields such as power plant, transformer substation, petrol chemical industry , metallurgy , manufacturing industry , airport, residential area, etc., to control and protect the electric equipment, especially , It is used for the occasion that needs infrequent operation at rated current or multi-breaking short circuit current, may be mounted in the indoor air insulating switchgear like type KYN28 or KYN96, ABB type ZS series, etc. This circuit breaker is standards asGB1984-2003 AC high voltage circuit breaker ,JB3855 3.6-40.5Kv indoor AC High voltage circuit breaker ,DL/T403 Specification of 12-40.5Kv indoor High voltage vacuum circuit breaker for order as well as IEC60694. This circuit breaker is made with mature APG technology . The application of VD4terminal buffer guarantees the indoor terminal is ever more reliable in nay operation environment. VD4 can fully meet the requirement of GB, DL, IEC, DIN, VDE as well as standards of other advanced industrial countries.
Service environment:
a) Air temperature: Maximum temperature: +40ºC; Minimum temperature:-25ºC
b) Humidity: Monthly average humidity 95%; Daily average humidity 90%.
c) Altitude above sea level: Maximum installation altitude: 2500m
d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
e) No frequent violent shake
Main technical specifications:
Note: For short circuit breaking current & rated current is optional by clients.
ATTENTION:
1.The payment term: We accept TT,30% deposit and 70% balance against copy of BL.
2.The delivery time: Usually it will take about 15-20 days.
3.The standard of package: Usually use strong plywood case for protection.
4.The material of transformer: We have two types, one is with copper and another one is with aluminum. It depends on your requirement. In fact, those two have difference if normal work well. Only except the long life. Copper is better and also higher price.
5.The logo: If you have good quantity, it absolute no problem to do OEM.
6.Our market: our products are popular in Indonesia, Philippines, Russia, USA, Middle East and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefit from our cooperation..
