What is a Strain Relief?
Strain Relief Description
Strain reliefs or strain relief bushings, like their moniker suggests, offer support and relieve strain to areas of cables that are prone to cracking or breaking due to frequent movement. Effective strain reliefs prevent any electrical loads applied to the cable from being transferred to conductor terminations. Also called bend reliefs, strain reliefs are integral part of electrical reliability in products and ensure overall performance.
Strain Relief Applications
Strain reliefs are often attached to a plug or connector that connects a wire to an electrical outlet. Strain reliefs may also be used at contact points or bends in the wire to prevent wear and tear on cables. Many strain reliefs have a series of ridges which allow for greater flexibility at vulnerable areas of cables or cords. It should be noted though, that strain reliefs are extremely customizable and most manufacturers can design them to meet the requirements of the end product.

- Altech
- Amphenol
- Heyco

What is Heat Shrink Tubing?
Heat Shrink Tubing Description
Heat shrink tubing (heatshrink) is plastic tubing used to protect cables and wires from harsh environments. When heat is applied to the tubing, it shrinks in diameter and length causing the tubing to tightly wrap around the inserted wire(s).
Heat Shrink Uses
While the primary function of heat shrink tubing is to protect wires from harmful elements like oil and dust there are several other functions and benefits. Heat shrink tubing is also utilizied to insulate wires, bundle wires together, color-code wires for organization, relieve strain and stress on cables and neatly terminate the ends of braided sleeving.
Heat Shrink Sizing
Heat shrink tubing is available in many sizing options. Depending on the manufacturer, the shrink rate may be stated as a ratio or percentage. For example heat shrink tubing with a shrink ratio of 3 to 1 will shrink to one third of the original diameter. The expanded (original) diameter of the heat shrink should be 20-30% larger than thickest portion of of the application.
Heat Shrink Tubing Manufacturers
Heat shrink tubing was first invented in the late 1950’s by Raychem Corporation founder, Paul Cook. Today there are countless options available from many different manufacturers. Leading manufacturers include:
- 3M
- HellermannTyton
- Alpha Wire
- Panduit
- Dunbar
- Essentra (formerly Richco)
- Thomas & Betts
- Molex
- TE Connectivity (Raychem)
- Qualtek
