Product Advantages
Excellent electrical performance
- can withstand higher voltage, high insulation resistance, low dielectric loss, good corona and arc resistance.
High mechanical strength
- can withstand certain mechanical stress, such as vibration, impact, etc., to ensure structural stability in harsh environments.
Strong corrosion resistance
- the materials used have good corrosion resistance and can resist erosion by various chemicals and humid environments.
Easy installation
- reasonable structural design, simple and quick installation, can reduce installation costs and maintenance workload.
Product Applications
Shielding bushing are used in power distribution devices and high-voltage electrical appliances in power stations and substations to allow wires to pass through grounding partitions, walls or electrical equipment casings, supporting the conductive parts to insulate them from the ground or casing.
