This 35kV insulated cross-arm is engineered for medium-voltage grid applications. Its manufacturing demands precise design, sophisticated technology, and strict quality control, which reflects the high level of the producer. The product complies with relevant IEC standards for post insulators as it is essentially a type of post insulator, yet it has its own particularities. Unlike common post insulators that are usually installed vertically, the insulated cross-arm is installed horizontally or at an angle to the horizontal plane. Therefore, it requires stronger bending resistance and also has a demand for lightweight design.
During operation, it not only insulates the conductors but also withstands various mechanical loads such as those from wind, ice, and the weight of the conductors. The hollow-out cuboid structure helps to optimize the weight without sacrificing strength. The tie-top end fittings enable a firm connection with the conductors.
It exhibits remarkable electrical insulation properties and mechanical durability, can endure different environmental conditions, and is highly valuable in medium-voltage power distribution, especially in areas with complex environmental factors.
Standards:
IEC 61952-1-2019; ANSI C29.18
Specifications:
Application:
It is mainly applied on the poles or towers in the power grid, especially in medium-voltage distribution lines. Its main task is to offer stable electrical insulation and mechanical support for the conductors, which is crucial for the reliable operation of the power distribution network and the supply of electricity to end-users.
Features:
● High Reliability:
Meeting the specific requirements of the medium-voltage grid, it can work stably over an extended period, minimizing the frequency of maintenance and guaranteeing the uninterrupted power distribution.
● Special Design for Insulation and Mechanical Loads:
