SR3 - SE6

Description

The SR3 and SE6 disconnectors are devices for outdoor installation for direct pole mounting. The SR3 disconnector is made with a rotating opening system and offers the possibility of passing through the medium voltage line. The SE6 disconnector is made with a hinged opening system and offers the possibility of vertical installation, for the junction of the medium voltage line. On request it can be equipped with an earthing switch with independent or interlocked operation. The operating mechanism of both disconnectors is hand operated. The operation can be carried out with a insulating rod or with a system of levers that can be coupled to a shaft (one 3 m long shaft or two 3 m long shaft with section breaker).

Fields of application

SR3 disconnectors are normally used for disconnecting overhead lines. SE6 disconnectors are normally used for the isolation of connection lines. They are suitable for use in secondary distribution networks up to 24 kV.
