Features & Advantages
1. Low loss, low noise and high reliability.
2. Excellent dynamic thermal stability and high over-load capacity.
3. Simulation analysis was carried out for the core mould design, thus to greatly reduce noise level. Simulated lightning impulse wave process was carried out for HV winding mould design, thus to greatly improve product's anti-lightning impulse capability.



* Check list of maintennance


 1 Busbar and insulator Check whether there are sparking trace on the insulator’s porcelain. Winding insulation is damaged or connection is poor.
Check the color at the connection part of the busbar.

Insulator is damaged.

Insulator pollution is serious.

 2 Capacitor

Abnormal discharge sound.

Connection part is over-heating

Appearance abnormality

Internal fault

Operation voltage is 10% higher than the rated voltage

Operation current is 30% higher than the rated current.

Over-load operation
 3 Apparatus, Signal, Indicator No indication or the indication is not correct Device is damaged.
 4 Lightning Arrester Crackle Device is damaged. It should be replaced
Surface pollution Too much dust on the surface.
Tilting, cable terminal or earthing terminal is loosing Mounting is not firm.
5 Contactor Too much noise

The iron core top surface is not even.

There are pollutions on the surface.

Over-heating, burning or abnormal smell from the contact.

Overload operation.

Imperfect cable connection.

The contactor was once burned-out under large current.


SF6 load switch

Pressure gauge

The device does not conform to the factory specifications SF6 gas leakage


If possible, use infra-red gun to detect the temperature of various electric components. In case of temperature abnormality, solve the problem in time.
