High Voltage Cable Branch Box 35kV

Short Description

Outdoor 35 kV cable branch box with fully insulated and fully shielded design to ensure safe and reliable high-voltage power distribution, featuring IP55/IP65 rated environmental protection.

Description

This high‑voltage cable branch box is designed as a compact outdoor 35 kV distribution cabinet for underground and renewable energy networks. Its sealed, fully insulated and fully shielded design provides touch‑safe operation and ensures personnel safety during switching and maintenance. The box uses high‑quality insulation materials and copper busbars to deliver stable power transfer while preventing partial discharge and moisture ingress.

A rugged enclosure with IP55/IP65 environmental protection shields the internal components from dust, water and corrosive atmospheres. The modular construction allows flexibility in configuring feeder circuits, and heavy‑duty connectors provide quick plug‑in termination for incoming and outgoing cables. The branch box can be pole‑mounted or pad‑mounted, and it integrates seamlessly into urban power distribution systems, renewable energy collection points and industrial corridors.

The system adheres to IEC 62271‑200 standards and supports rated voltages up to 40.5 kV and currents up to 1250 A. Its fully insulated, gas‑free design eliminates the need for SF₆ gas and reduces maintenance requirements, offering long‑term reliability and cost efficiency.
