Complaint
Distribution switchgears, also known as feeder switchgears or substation switchgears, are used to distribute electricity from a power plant or substation to customers. They are a key component of the power grid infrastructure and play a critical role in maintaining reliable power delivery.
Qinghao Electric is developing and producing a variety series including LV MV and HV switchgears including below: KYN, XGN, HXGN, XGW, DFW, GGD, GCK, GBD, PGL MNS and so on. Our switchgears are equipped with high quality fuses, circuit breakers, relays, and control systems to protect and control power flow.
Main Characteristics
Qinghao switchgear meets the requirements of GB/T11022, GB/T3906 and IEC60298 related standards. It has the interlocking device function to prevent below:
1. pushing and pulling circuit breaker truck when on loading.
2. miss opening and closing circuit breakers.
3. closing the circuit breaker when the grounding switch is in the closed position.
4. miss entry into the live compartment,
5. miss closing the grounding switch when it is live.
Advantages
1. Fully insulated, fully sealed structure, no insulation distance, reliable to ensure personal safety.
2. Dustproof, flood-resistant, corrosion-resistant, maintenance-free, suitable for any harsh environment.
3. The combination is extremely flexible, simple to install and easy to operate; Branches can reach up to eight outlets.
4. Compact structure, small and beautiful appearance, double-layer box, service life can reach more than 20 years.
5. Under the premise of not affecting the operation of the main network, realize regional power outage maintenance and reduce the scope of power outage.
6. Optional short circuit fault indicator, arrester, current limiting fuse, etc., to meet the various needs of users.
7. Box material can be selected: ordinary steel with green, mirror stainless steel, stainless steel with green, etc.
Applications
Mainly used for the substation and power distribution system of electric power distribution, control, protection,measurement and supervision.
Service Environment
