Product Introduction
12kV bushing insulator is suitable for three-phase AC systems power stations and substation distribution equipment with a rated voltage of 12kV and a frequency of 50~60Hz. It is used to allow conductive parts to pass through partitions, walls, or other grounded objects, and serves as an insulation support and fixed connection between external conductors (busbars).
A 12kV bushing insulator is an insulating component used at a 12kV voltage level. Its main function is to allow conductors to safely pass through grounding barriers (such as switch cabinet walls and transformer enclosures) while ensuring electrical insulation and mechanical support.

Product Advantages
12kV 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.
