Stress Cones

Description:
Stress cones are a means of preventing insulation failure at the termination of a shielded cable caused by the high concentration of flux and the high potential gradient that would otherwise exist between the shield termination and the cable conductor

Construction:
A stress relief cone is made by increasing the separation between the shield termination and the conductor cable. Precautions must be taken to insure a termination which is free of dirt and foreign matter and insulating compounds and tapes must be applied in a prescribed manner. Potheads may also be used with the stress relief cone termination.

Application:
Typical uses for stress cones would be in pad-mounted transformers, switchgear, high-voltage motor installations or in most applications were shielded cable is being terminated.

Installation:
Normally Stress Cones are not provided by the motor manufacturer but are made by the motor installer. When a customer requires stress cones, the manufacturer will supply a conduit box with sufficient room for the stress cone on each lead.
