Ground Preformed Strain Clamp
FUNCTION
Dead-ends are designed to hold insulated cables and bare homogeneous cables in transmission and distribution construction. Mechanical strength for these dead-ends are superior to that of homogeneous cables.
But, for steel-core cables the strength is approx the same as the breaking load of the aluminum strands.
This products are manufactured with aluminum covered steel for ACSR and homogeneous conductor, with copper covered steel for copper conductors and galvanized steel for direct application on insulator conductor.
These transmission and distribution dead-ends must be used with a clevis thimble and insulators which have smoothly contoured surfaces adequate groove widths and loop diameters.
ORDERING INFORMATION
When ordering, please specify:
-conductor type, stranding, breaking strength, out layer direction
NOTE:
The out layer direction of transmission and distribution dead-ends must be same as that of the outer standing of the conductor to which it is applied.

-For insulated and covered cables
MATERIAL
Dead-ends:
High-tensile galvanized steel.
APPLICATION
Suited for the full tensioning of insulated conductors on transmission and distributribution lines.
