Cross Arm Brackets，also call M-type cross arm.

The essential components in overhead power distribution systems, providing structural support for conductors, insulators, and associated hardware on spun concrete poles or wooden poles. These brackets ensure proper conductor spacing, mechanical stability, and electrical insulation, making them critical for reliable power transmission and distribution.

This Single Cross Arm Brackets,Used for single-phase or low-voltage lines,simple and economical.

Construction and Materials

This model from Handan Jinmai is made of low-carbon steel with a hot-dip galvanized surface (our zinc coating exceeds the average minimum zinc coating index).

Features of galvanized steel:

*High strength and durability；

*Cost-effective but requires corrosion protection；

*Commonly used in standard distribution lines.

Size choosen:

Handan Jinmai's experienced engineers can design dimensions based on product images or crossarm usage scenarios, ensuring optimal material selection and pricing. Of course, we can also manufacture according to customer drawings. 

Handan Jinmai has upgraded its punching technology, utilizing information technology for control and laser drilling, resulting in more aesthetically pleasing and standardized products.

Applications

Cross arm brackets for spun concrete poles are widely used in:

*Overhead Power Distribution Lines (11kV, 33kV, 66kV).

*Street Lighting and Utility Poles.

*Telecommunication Line Support Structures.

*Railway Electrification Systems.

Conclusion

Cross-arm supports play a vital role in ensuring the mechanical and electrical integrity of overhead transmission lines. Proper selection and installation are crucial to the long-term reliability of the distribution network.
