10kv Epoxy Resin Insulator for Medium Voltage Switchgear

12kV Epoxy Resin Insulator is manufactured using high-performance epoxy resin material through APG (Automatic Pressure Gelation) vacuum casting technology.

This advanced process ensures dense internal structure without air bubbles, providing excellent insulation reliability and long service life.

In medium-voltage power systems, the insulator functions as a "mechanical support and electrical isolation bridge" - supporting live conductors (such as copper busbars) while completely isolating energized parts from grounded cabinet structures.

The product is widely used in indoor switchgear, RMU, distribution cabinets and substations.

Main Features & Advantages

1) Excellent Electrical Performance

• High dielectric strength and volume resistivity

• Power frequency withstand voltage: 42kV / 1 minute

• Lightning impulse withstand voltage: 85kV

• Extremely low partial discharge level

• Long-term operational stability

Advanced APG casting ensures superior insulation integrity and prevents internal defects.

 

2) Strong Mechanical Strength

• High compressive and bending strength

• Lightweight design (approx. 30% lighter than ceramic insulators)

• Excellent impact resistance

• No shattering or splashing under mechanical shock

Suitable for supporting busbars and conductors under mechanical stress during operation.

 

3) Superior Environmental Adaptability

• Excellent moisture resistance and chemical corrosion resistance

• Hydrophobic surface performance

• Stable operation under humid, salt spray, or polluted environments

• Ribbed shed design increases creepage distance (≥20mm/kV)

• Effectively reduces surface flashover risk

 

4) Easy Installation & Maintenance-Free

• Compact structure suitable for indoor switchgear

• Simple bolt fixing installation

• Maintenance-free under normal operating conditions

• Only periodic surface cleaning required

Application Areas

• 12kV Indoor Metal-Clad Switchgear

• Ring Main Unit (RMU)

• Busbar Support System

• Distribution Cabinets

• Substations
