Reasons Why Heat Shrink Is A Purposeful Product For Electrical Engineers
Electrical engineering often includes numerous connections and joining of components to allow fluid flow of current which calls for an appropriate connectivity method. Heat shrink provides an effective option for termination, sealing, seams, identification as well as insulation. It basically refers to a type of plastic tubing (expanded and extruded) that is designed to contract when exposed to heating. Heat shrink tubing are mostly used for electrical, electronic, cable management and telecommunication industries for many purposes both for interior and external connections. They are also used by plumbers to connect tubes and pipes. Heat shrinks are made of nylon or polyolefin materials that are designed to shrink to product a watertight seal and thereby clamping and joining the material inside.
Purpose of Heat Shrink in Electrical Engineering
Professional electrical engineers have great utility for heat shrink tubing mainly because they can be moulded for several different properties to suit varied connections. They can be used for various electrical applications but most commonly to join wiring.
Heat Shrink Application
The extruded/un-shrunk tubing is usually fitted and positioned to where the joint meets. It is then heated to contract and make connections robust and safe with additional use of lubricants to ensure easy joining without compromising the tubing. They also come in varied shrinking ratios depending on the type of connection needed.
Some benefits that electricians can experience in the use of these products include;
Offers protective sealant – Heat shrinks can be used to provide protection against dust and water for electrical cables in cars and other large transport vehicles.
Insulation – There are flame retardant versions of heat shrink tubing that are perfect for insulating electrical cables from flames and chemicals. This can be used in vehicle and boat connections to prevent fires during over-heated engineering malfunctions.
Identification – Heat shrink provide excellent identification that can be used to indicate places where a different cabling component begins. They are also used to identify joints as well as different cables since they come in various colours that can be used to route wires in confined areas.
Grip and strain relief – Heat shrink tubing can be used to form grips that fit well in electrical holding equipment. This is also an alternative for worn out grips and strained cables.
Soldering – Electricians have adapted to using heat shrink tubing instead of soldering which is less efficient. They offer perfect insulation by covering/coating the seams in addition to the exterior casing that acts as a guard.
Heat shrink is a versatile electrical accessory that is of great utility in both industrial (telecommunication, plumbing) and home application. They are made of heat retardant materials that are effective in preventing fire spread from surges and insulate cables from energy loss. Their application range from general small scale cable repair to industrial manufacturing of vehicles including cars and HGVs. The availability of offering a variety of colours and identification codes greatly helps the distinction as well as connectivity.
