Purpose of the development: Withdrawable elements with vacuum switches BB / TEL-10 are intended for the reconstruction of the complete switchgear (KRU) in cases where the modernization of the old roll-out elements using switching modules BB / TEL-10 impractical for technical or economic reasons. In most cases, upgrading does not require the display of switchgear operation. The reconstruction is to replace the old to the new withdrawable unit - is a simple and less time consuming way of modernization of KRU.

Advantages over analogues: High reliability; No need for maintenance throughout the service life; Can be installed in any switchgear cabinets medium voltage; A wide range of operating supply voltages; Low power consumption of the auxiliary power supply network; Functions of remote signaling; Certification of products for compliance with national standards of consumer countries and international standards; A wide range of services and customer support throughout the entire life cycle of products; Environmental cleanliness and safety for the environment.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
Withdrawable part RE / TEL-10 with vacuum switches BB / TEL supplied by us, as a rule, enterprises and factories producing new complete distribution systems, as well as for the replacement of in-use low-oil breakers type VC, TBE. When ordering, you need to specify exactly by the manufacturer and the type of switchgear used, the diameter of the main circuit contacts withdrawable unit, the nominal parameters of the replaced switch and control voltage substation. For switchgear with withdrawable elements types: CM-1 KM-1F K-47 K-49 K-59 K-104 (M) Metal-clad switchgear 6 (10) A
