RC-CFSR Constant Force Spring

Product Overview

RC‑CFSR Constant Force Spring is designed to provide continuous radial pressure for reliable shield and armor grounding connections in power cable accessories. The spring is manufactured from fatigue‑resistant stainless steel that has been heat‑treated and precision‑coiled to maintain stable mechanical force during long‑term service.

The constant force spring is typically used for solderless shield and armor connections during power cable splicing and termination. By applying uniform pressure around the cable shield or braid, the spring ensures reliable electrical contact and secure mechanical fixation.

RC‑CFSR springs are easily installed by rolling them onto the cable sheath connection area. The spring structure automatically applies constant pressure around the cable circumference, improving connection reliability and simplifying installation.
