What are the main devices used in a high-voltage electricity transmission system?

A1: The main devices used in a high-voltage electricity transmission system can be broadly categorized as:

• Conductors: The wires or cables that carry the electrical current.

• Insulators: Devices that provide electrical isolation to prevent the current from escaping to the support structures.

• Switchgear and Circuit Breakers: Equipment used to control, protect, and isolate the electrical circuits.

• Transformers: Crucial devices in substations that step up or step down the voltage for efficient transmission and safe distribution.

• Substation Equipment: A wide range of devices including surge arresters, relays, and busbars that manage power flow and protect the system.

Our company, Ningbo Changshi, specializes in manufacturing the high-quality tools and equipment for installing and maintaining all these critical devices, including overhead transmission line (OHTL) tension stringing equipment and underground cable laying equipment.
