S11M is a 12kV threephase (D11M is single phase transformer) oilimmersed transformer. The iron core is made of quality cold rolled silicon steel sheet, while the coil is made of quality oxygenfree copper, featuring good outlook and safe running. The adoption of compress wire in winding makes lower losses and enables it to
have a good short circuit withstand capability. The products are widely used in industrial and agricultural power networks.

Features
■ HV side rated voltage from 7.2 to 12kV
■ Transformer capacity from 30 to 2500kVA
■ Single phase or three phases

air insulated switchgear for up to 24kV secondary distribution network. It is suitable for a lot of applications, like compact transformer substations, airport, industrial & mineral enterprise and residence area, etc. All functional units can be easily installed side by side. Since the switchgear is highly modular type, it can meet the needs of different clients by providing multiple configurations.

Features
■ Up to 24kV,...630A,...20kA/4s
■ Air insulated & 3 position 8F6 load break switch
■ Vacuum circuitbreaker
■ Selfpowered relay available
■ Single phase or three phases

HZF fault passage indicator is used on overhead lines to assist in the rapid location of faults on Medium Voltage networks (6~35kV). When the current exceeds a preset level, the indication is given by means of both a mechanical flag and high-intensity LED. HZF is mounted to the overhead lines using a standard hot stick. A spring-loaded clamp mechanism fixed the unit to the line, and prevents it from movement due to high winds, etc.
Features
■ Flag & Hi Power LED 360°lndication
■ Automatic reset on line re-energization
■ User-selectable trip level, response time, timer -reset & auto-reset period
■ Line mountable with standard hot-stick
■ Self-powered from long-life battery & Communication available
