What equipment is used to protect and control a 132 kV substation?

2025-08-12

A 132 kV substation is a complex hub that steps down voltage and distributes power. Its operation is managed by a suite of critical equipment:

  • Bus Bars: These are the central connection points for incoming and outgoing lines, typically made of aluminum or copper.

  • Circuit Breakers: These devices automatically interrupt the flow of electricity during a fault to prevent damage to other equipment.

  • Isolators and Disconnect Switches: Used to physically isolate sections of the substation for maintenance, ensuring worker safety.

  • Surge Arresters: These are installed to protect the substation from overvoltage caused by lightning strikes or switching surges.

We supply a comprehensive range of Overhead Tools and Accessories that are vital for the construction and maintenance of these substations, including all the necessary grounding equipment, insulated tools, and cable laying equipment to ensure safe and reliable connections.
