Product Advantages

40.5kV bushing insulator has many advantages:

Excellent Electrical Insulation Performance

Effectively prevents accidental contact between conductive parts at different potentials, avoiding electrical faults such as short-circuit. It can withstand specific voltage levels, ensuring the safe and stable operation of the power system.

Mechanical Protection

Protects wires or cables passing through walls from mechanical damage such as compression or friction from the wall. It also helps prevent external impacts and vibrations from damaging the internal wiring.

Superior Sealing Performance

Prevents dust, moisture, and other contaminants from entering the bushing, which could affect its electrical performance. Good sealing also helps prevent small animals from entering, reducing the risk of electrical accidents.

Easy Installation

The structure is relatively simple, making the installation process easy, saving time and labor costs. It can adapt to different installation environments and wall structures.

Product Applications

The porcelain wall bushing is used in power distribution equipment and high voltage electrical equipment in power stations and substations. It allows conductors to pass through grounded partitions, walls, or the casing of electrical equipment, supporting the conductive parts to insulate them from the ground or casing.
