High Tension Long Rod Croos-arm Insulator Composite


Product Description

This kind of product is applied to urban net technical reconstruction; it can effectively boost power transmission using urban narrow corridor areas, lower tower height, save many pecuniary resources and materials. Because of the high bending strength, it can avoid the porcelain cross-arm having continuous fracture accidents easily, with good anti-pollution, and the products of porcelain cross-arm cannot be instead of it.

Tips: Since we (TCI) have many different models and types,providing exact model or detailed technical specification in your inquiry will largely help us finding your a better solution within less time and reducing your communication cost.

This product is applicable to the technical reform of city network,which can effectively use narrow corridor

area of city to boost power transmission,can reduce the height of tower,save lots of financial and material

resources.Because of its high bending strength,it can prevent fracture accidents which easily happen in

porcelain cross arm insulator,and it has good pollution resistance,porcelain cross arm can not be replaced.

Product characteristics

1.No flaw,crack in the surface and interior,each bar color uniform(green or light yellow).

2.Can withstand the sawing,milling,planning,drilling,lathe and other mechanical processing.

3.Internal thread can be tapping with screw tap,external thread can be polished,but not allowed to bear overload.

4.It has good damping,creep resistance,fatigue resistance,fracture resistance ,high temperature resistance,stress corrosion resistance etc.
