Wholesale Interphase Spacer, Interphase Spacer Manufacturer

In electrical power systems, the Composite Interphase Spacer plays a crucial role. When the power system is in operation, the Composite Interphase Spacer ensures the stable operation of the transmission lines. It maintains a proper distance between phases and effectively suppresses the conductor galloping. In windy or other adverse conditions, it can make the conductors interact with each other in a coordinated way to avoid excessive movement and keep the electrical clearances within a safe range.

It's mainly used between two phases of three-phase alternating current, which means it has to bear the line voltage instead of the phase voltage. For example, in a power line with a phase voltage of 220kV, the Composite Interphase Spacer needs to withstand a line voltage of 380kV. And in a 110kV phase voltage circuit, it has to endure 190kV of line voltage. Thus, compared to long-rod insulators and post insulators with the same rated voltage, the Composite Interphase Spacer has stricter requirements in design, manufacturing, and inspection.

Interphase Spacer Components:

● Insulation Body:

Made of high-quality composite materials with excellent insulation performance and mechanical strength. It not only provides reliable electrical insulation between phases but also can withstand the mechanical stress from the conductors, ensuring long-term stable use in the complex environment of the power grid.

● Connector Fittings:

These are precisely designed to firmly connect the spacer with the conductors. Made of strong and durable metal materials, they have good corrosion resistance to ensure reliable connection under different weather and load conditions.

● Anti-vibration and Damping Structures (in some models):

They work together with the main body during the vibration of conductors caused by wind or other factors. By absorbing and dissipating the vibration energy, they reduce the impact on the spacer itself and the entire transmission line, enhancing the overall stability and service life of the system.
