Product Description

Construction & Materials

1) Insulators: Fabricated from high-strength ceramic or composite materials, these insulators provide excellent electrical insulation and mechanical robustness, resisting voltage arcing and environmental corrosion.

2) Conductive Components: Made from copper or copper alloys, the contacts and terminals ensure low contact resistance, efficient current conduction, and long-term durability.

3) Frame & Mechanisms: The metal frame features precision-engineered switching mechanisms, enabling smooth, synchronized operation of multiple poles for reliable circuit isolation.

Core Functions
  • Enables reliable electrical connections in the primary main circuit of handcart-type switchgear, while providing robust insulation to prevent leakage and short circuits.
  • Withstands high-voltage power frequency (6–12kV) and lightning impulse voltages, ensuring stable operation under extreme electrical conditions.
  • Shields against electromagnetic eddy currents, reducing interference and maintaining circuit integrity in complex power systems.
  • Extends creepage distances through optimized structural design, enhancing insulation reliability in humid or dusty environments.
  • Facilitates secure plug-in connections with handcart components, ensuring seamless contact during operation and maintenance.
Applications
  • Widely used in 3–12kV substations (including indoor distribution stations and box-type substations) for power isolation and system switching.
  • Integrated into high-voltage switchgears, supporting power distribution in industrial and mining enterprises, commercial buildings, and residential areas.
  • Applied in power supply systems of key infrastructure such as railways, airports, and data centers, ensuring stable power transmission.
  • Suitable for renewable energy projects (solar and wind power plants) as a safe isolation component in medium-voltage distribution networks.
