Product Features

Operation Safety:

We provide special security for our users through the following security measures:

integrated three-station load switch

circuit breaker adopts load switch instead of isolating switch, which is safer and more reliable. The fully enclosed design on the primary side provides accidental contact protection. The mechanical interlocking live display that meets the requirements of five defenses can provide live indication of incoming and outgoing lines and reliable operation: fully enclosed design, all 10kV switches and bus conductors are sealed in an air box welded with 3mm stainless steel plate; Equipped with silicone rubber cable plug to realize full insulation and full sealing of cable head, thus free from dust, moisture, small animals and other external environments affect the spring energy storage operating mechanism. The analog line diagram of the manual or electric operating panel can provide switch position indication. The cabinet is made of galvanized plate. The surface is electrostatically sprayed to enhance corrosion resistance. The pressure gauge monitors the safe pressure range of SF6 gas in the cabinet.

economy: maintenance-free and highly reliable service life of up to 20 years

scheme: a variety of line mode, a variety of combination mode, the use of insulated bus, flexible design

Widely used: large feeder capacity, small footprint, suitable for a variety of applications.

Design Description

SM6-12 fully enclosed and fully insulated inflatable ring network switchgear is installed on a galvanized sheet frame, and the switching unit is in an SF6 air box, which is made of corrosion-resistant and non-magnetic 3mm thick stainless steel plate. The SF6 gas tank is a "sealed pressure system" that can operate for 20 years under normal operating conditions. When the SF6 gas is working normally, the pressure is 0.015 ~ 0.04mpao. The gas box is equipped with a pressure release device. When the pressure is too high, the gas can be released from the bottom or rear.
