Check up to five results to perform an action.
larger image
Type-JB Strain Insulators are made of the highest grade of wet ware porcelain. They are rugged and have a low susceptibility to mechanical breakage. The holes and grooves are straight thus making assembly easy even with stiff guy strand.
Mechanical strength ratings are values developed with hard drawn copper or mild steel cable.
The type of strand and method of attachment will have a marked influence on the strength developed.
These insulators are intended primarily for guy or span wire insulation. They may also be used for low-voltage dead ends with the use of the clamps and fittings.
