Wholesale Insulated Cross-arm, Insulated Cross-arm Manufacturer

In electrical power systems, the Composite Insulated Cross-arm plays a crucial role. It serves as an important component that supports conductors and helps maintain proper spacing between them. Compared to other insulators used in the power system, it has its own special technical requirements, selection principles, and product characteristics.

To produce a qualified Composite Insulated Cross-arm, strict requirements are set not only for electrical strength and tensile load but also for the anti-torsion and anti-bending strength of the core rod and fittings. Moreover, as it is a substitute for traditional cross-arms, its contribution to lightweight design becomes a key assessment indicator. This is because a lighter cross-arm can reduce the load on supporting structures and make the overall installation and maintenance more convenient.

During the operation of the power grid, the Composite Insulated Cross-arm undertakes the task of firmly supporting the conductors and withstanding various forces from different directions, such as wind loads and the weight of the conductors themselves. It needs to maintain its structural integrity and insulation performance under long-term use and different environmental conditions.

Composite Insulated Cross-arm Components:

● Insulating Body:

Made of high-quality composite materials with excellent electrical insulation properties and mechanical strength. It provides reliable insulation between the conductors and the supporting structure, ensuring the safety of the power transmission system.

● Core Rod:

It is the key part that bears the main mechanical load. Made with materials that have high strength and good durability, its anti-torsion and anti-bending performance are carefully designed to meet the requirements of different application scenarios.

● Fittings:

These are used to connect the cross-arm with the conductors and the supporting poles. They are made of sturdy metal materials with good corrosion resistance and are precisely designed to ensure a firm and reliable connection, enabling the cross-arm to play its role effectively.
