Selection of constant force spring for cold shrink cable accessories

The application environment of the constant force spring is the same as that of the cable accessories. The outside is generally wrapped with some strips to prevent the axial displacement along the cable. In the process of use, it is wrapped in the whole joint or terminal inside and will not be in direct contact with the moisture, but it is easy to contact the moisture when the protective layer is damaged, plus the heat during the operation of the cable and the escape of various insulation and sheath materials. The formation of a very harsh small environment, so the constant force spring cable accessories corrosion resistance requirements are very high.
