This products for the urban net rebuild can effectively solve the shortage of corridor in urban power line, reduce the pole height and economy lots of financial and material resources. Because of the high strength, to avoid the porcelain cross-arm causes to conc atenate breakage of high strength accident, and fine anti-pollution. And the products of porcelain cross-arm cannot instead of it.

Crossarm products are used more domestically. We can make cross arm insulators from 10KV to 138KV.
Some crossarm products use the same environment as post insulators.
All insulators are produced in the same way, the difference lies in the choice of fittings and the way of crimping.
