In general, heat shrink tubing is a common element in most electrical setups that insulates electrical components from external factors such as moisture, dust, abrasion, and sharp objects that might otherwise damage wires and electrical components. This type of damage ultimately results in shorts and failures.When used as a protective covering, heat shrink provides protection from abrasion, cutting, scuffing, and low impact situations. It's able to be used with virtually any design of conductor. Heat shrink can also be used to create cable entry seals providing protection from the surrounding environment
