This type of dead ends is a fast, simple safe method for retaining or securing cables such as staywires, groundwires etc.
Standard products have an open helix loop but they can be supplied with a cabled loop to prevent slackening of the line after prolonged installation.
The dead ends are made of material compatible with the cable to which they are applied
The dead ends with helical wires are used to given an even distribution of force ever a wide surface preventing strain concentration and potential damage to conductors.
Its breaking load exceeds that of the conductor to which is applied.
The layer direction of distribution-grip dead ends must be the same as that of the outer stranding of the conductor to which it is applied.
When ordering, please specify:
-conductor type,stranding,breaking strength and lay direction
-groove width and diameter of fitting used.
