How To Protect Electrical Cables with Heat Shrink Sleeves & Improve the Performance of Electrical Installation

Heat-shrinkable sleeving is widely used to insulate, organise, and protect electrical and electronics cables in complex electrical installations and sensitive electronic designs. Gala Thermo offers a range of heat shrink tubes also called heat shrink sleeves to provide an advanced solution to protect your cable with dependable insulation.

A Brief About Heat Shrink Sleeves/Tubes

Heat shrink tubes are being used in different industries including automotive, IT, Telecom, medical, aeronautical, defence, construction, and other industries for over the decades. Heat shrink tube is a common element in most of advanced engineered electrical setups; it insulates electrical components from environmental and usage factors such as abrasion, sharp objects, moisture, dust, impacts, etc. that might damage the wires, electrical components, components, and machinery.

What is a Heat Shrink Tube?

Made of high-quality cross-linked polyolefin material, heat shrink sleeves form a protective seal shrinking tight around the object when heated.

What Are the Common Applications of Heat Shrink Tubes?

Heat shrink sleeves are used not only in electrical installations to secure cable joints, these are finding innovative applications in different segments. Some of the common applications of heat shrink sleeves are-

  • Cable jacketing
  • Roll covers
  • Sealing temperature probes
  • Chafing sleeves
  • Electrical insulation for wire bundles
  • Light duty bearing surfaces
  • Bundling loose wires
  • Protecting connectors
  • Wire identification by colour-codding
  • Providing extra grip in sports equipment
  • Repairing of fishing rods

How To Choose Right Heat Shrink Tubes to Protect Cable Joints Or Other Objects?

The leading manufacturers and suppliers of heat shrink sleeves offer a wide range of heat shrink sleeves to meet the diversity in the intended applications. Heat-shrinkable sleeves are available in a variety of materials but heat shrink sleeves of cross-linked polyolefin are more in demand. Depending on the type of sleeve chosen, these may have particular properties: self-extinguishing, halogen-free, heat resistance, shrink ratio, heat-transfer marking, etc. The critical selection parameters are-

  • Wall thickness: Thin wall tubes; medium wall tubes; heavy wall tubes, red insulation tubes
  • Shrink ratio: 2:1, 3:1 or 4:1 (depending on the sheath)
    • Colour: A range of colour for cable identification
    • Packaging: Reel, bar, coil, distribution box, sleeves, etc.
    • Customization

The Top Variants of Heat Shrink Sleeves You May Consider to Insulate Wires, Cable Joints, Terminals & Components

        GSC Series: Heat shrink sleeves of this category provide electrical tough insulation and dependable protection for in-line components. These are commonly used for light duty wire harnessing, bus-bar insulation, and strain relief for electrical wire connections.

GSC/YG Series: Extremely flexible, flame-retardant, thin wall with yellow and green striped heat shrink polyolefin tubes of this category are highly used for ground lead applications. These are manufactured with shrink ratio 2:1 to provide electrical insulation up to 3.3 kV.

Medium / Heavy Wall Tubes: GMW  heat shrink sleeves are used to provide environmental protection to low voltage cable terminations and connectors upto 3.3kV. Heavy wall tubes (GHW) are used for mechanical protection and outer sealing of straight through cable joints/ splices upto 36kV.

Non-Tracking Heat Shrink Tubes: These are used up to 36 KV. These offer exceptional insulation and long term service reliability.
