Product descriptions from the supplier
The RNF-40.5-02 is a 40.5kV-specialized manual operation mechanism designed for medium-voltage outlet line circuits, ideally paired with switchgear like SF6 gas-insulated cabinets or metal-clad outlet cabinets. It relies on manual actuation, ensuring reliable switching even without external power—perfect for emergency or remote scenarios where power access is limited.
Integrated with mechanical interlocking, it strictly prevents misoperations such as live switching or incorrect grounding, boosting operational safety. Its compact structure fits tight cabinet spaces, while the durable metal housing resists dust and moisture, adapting to substation, industrial distribution, and box-type switch station environments. Compliant with IEC and GB standards, it delivers stable performance for outlet line control, with a long mechanical lifespan to meet frequent operation needs.

Earthing closing and earthing switching operation
The operating handle is inserted into the lower part of the mechanism and rotatesabout 90 degrees clockwise. The load switch is closed to the ground circuit underthe action of the force of the mechanism spring, so that the main circuit closingoperation can not be performed at this time.The operating handle rotates about 90 degrees counterclockwise, and the loadswitch switches the grounding circuit under the action ofthe force of the mechanismspring, which can be used for closing operation or grounding operation.

7 Key Steps to Ensure Safe and Reliable Installation of Large Power Transformers1. Maintaining and Restoring the Factory Insulation ConditionWhen a transformer undergoes factory acceptance tests, its insulation condition is at its optimal state. Thereafter, the insulation condition tends to deteriorate, and the installation phase may be a critical period for sudden degradation. In extreme cases, the dielectric strength may drop to the point of failure, leading to coil burnout immediately upon energization.
