Cable repair supplies include cable repair kits and cable repair sleeves, which are used to mend cable and return them to proper working order. Cable repair sleeves repair damaged cable sheaths, provide protection against corrosion and mechanical stress and insulate and seal against the environment. Heat-shrink cable repair sleeves are also used to protect cable and have an inner wall coated with a hot melt adhesive. When the sleeve is heated, it shrinks back to its original size while also melting the adhesive, which creates a watertight seal and protects the cable from wear and environmental damage. Cable repair sleeves may be used in high- and low-voltage applications. They are generally used outdoors and aboveground.
