RMU Fuse Canister

KST series of small-sized thermostat and bimetallic thermostat dedicated for switchgears 10℃. It can automatically start fans or heaters and adjust temperature and humidity of the surrounding according to on-site situation. The contacts will output action indication signals, when ambient temperature is higher than pre- set temperature, the contact of controller will flip so to protect the equipments from being damaged.

CFJ series dehumidifiers are designed for the needs of various cabinet anti-condensation. Thermoelectric semiconductors with high thermoelectric conversion efficiency are used to make it small in size and high in dehumidification efficiency. It can effectively prevent the reduction of the insulation level of the equipment caused by condensation and adhesion on the insulation surface of equipment, so to avoid reptiles and flashover accidents caused by condensation of the switchgear cabinet.

Phase comparator PC-1 is an optional accessory for DXN series of high-voltage live line indicators.

HDZC-1-TR switch state comprehensive indicator is a smart multi-functional comprehensive dynamic switch-simulating and status-indicating device developed for the technology development of medium voltage system.

EKL4 Short Circuit Earth Fault Indicating Device indicates high voltage power line short circuit fault by detecting the 3 single-phase line-currents and short circuit currents, and the grounding fault by detecting the zero sequence currents. With visual or audible indicators, it helps line patrol staff to fast find out the location where there is a short circuit or grounding fault on the 3kV-40.5kV power distribution networks, switchgears or cable branching units etc.

MQZ4 D.C. electromagnet coil is used for the control circuit of D.C. 220V, which is dedicated for the hydraumatic solenoid valve of hydraumatic disc spring stored energy operating devices. The coil is thermo-plastic coated with superior temperature tolerance.

LMZK4 split core potential transformer is suitable for measurement of primary current, or for protection of electrical equipments such as microcomputer in 10KV and 35KV AC power distribution networks. It is widely used in fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus...and cable distribution boxes. The transformer can be directly installed at the inlet and outlet of the GIS or AIS cables. The semicircular ring core and secondary windings are vacuum poured by insulated resin. This CT is also used for signal acquisition for RTU or FTU.
