SPIDER Automation | WOER PVC Industrial Grade Heat Shrink Sleeve – 230mm × 1 Meter | Black 2:1 Shrink Ratio & Flexible Cable Insulation

Product Overview & Insulation Technology

The WOER PVC Industrial Grade Heat Shrink Sleeve (HST) is designed to provide insulation, bundling and protective coverage for electrical wires, cables, hoses and wiring assemblies. Its heat-activated PVC construction allows the sleeve to contract around a suitable component, creating a closer-fitting protective layer after heating.

Supplied in black colour with a stated 230mm diameter and 1-meter length, this sleeve can be cut to the required size for individual installations. The specified 2:1 shrink ratio means the material is designed to reduce to approximately half its original size after appropriate heating, helping it fit around compatible cables and assemblies.

The sleeve is specified for an operating temperature range of -40°C to 125°C. Its stated mechanical properties include tensile strength of at least 10.4MPa and elongation of at least 200%, supporting applications requiring flexible insulation and protective coverage.

Heat shrink sleeves are widely used for cable harnessing, strain relief, insulation, colour-coding and identification. When correctly selected and installed, this sleeve can also help protect covered wiring from regular wear and environmental exposure. The final protection achieved depends on correct sizing, surface preparation and installation conditions.


Technical Features & Performance Characteristics

  • 2:1 Heat Shrink Ratio: Designed to contract to approximately 50% of its original size when heated under suitable conditions.
  • 230mm Stated Diameter: Provides a wide sleeve format for compatible wiring assemblies and components. Confirm the actual measurement format before selecting it for a specific installation.
  • 1-Meter Supplied Length: Allows users to cut the sleeve into smaller sections according to installation requirements.
  • PVC Construction: Provides a flexible sleeve material for suitable insulation and cable-protection applications.
  • Wide Operating Temperature Range: Rated for operation from -40°C to 125°C under the stated specification.
  • Tensile Strength ≥10.4MPa: Provides mechanical strength for handling and protective coverage.
  • Elongation ≥200%: The specified elongation property supports flexibility during installation and use.
  • Black Insulating Sleeve: Provides a clean, neutral appearance for cable protection, wiring organisation and equipment assemblies.
  • Flexible Cable Coverage: Designed to contract around compatible wires, cable bundles and suitable components when heated.

Performance Advantages

  • Electrical Insulation: Provides an insulating covering for suitable wires, cable joints and electrical assemblies.
  • Neater Cable Assemblies: Helps bundle and organise multiple wires into a more compact and structured arrangement.
  • Strain Relief Support: Can provide additional covering around suitable cable transitions and connection areas.
  • Flexible Protective Coverage: The specified elongation property supports applications where the sleeve must accommodate flexible wiring assemblies.
  • Temperature Versatility: The stated operating range supports use in applications exposed to varying ambient temperatures.
  • Professional Appearance: Black material provides a consistent finish for electrical installations, equipment wiring and cable harnesses.

Industrial, Commercial & Electrical Applications

  • Electrical Wire Insulation: For covering and insulating compatible electrical wiring sections.
  • Cable Harnessing: For bundling and organising wires in electrical assemblies and equipment.
  • Strain Relief: For additional protective coverage around suitable cable joints and transitions.
  • Industrial Equipment Wiring: For insulation and protective covering in compatible industrial electrical assemblies.
  • Electronics Assembly: For cable organisation and insulation in suitable electronic equipment.
  • Automotive and Electrical Wiring: For compatible wiring harnesses and cable protection applications within the sleeve’s specified operating limits.
  • Power Cable Organisation: For grouping and protecting suitable cable assemblies.
  • Maintenance and Repair: For replacing damaged protective coverings or adding insulation to suitable wiring sections.

Installation & Operating Recommendations

  • Confirm Sleeve Dimensions: Verify the stated 230mm diameter and actual expanded sleeve geometry before selecting it for a particular cable or component.
  • Cut to Required Length: Cut a suitable section with clean edges, allowing sufficient coverage around the intended cable or joint.
  • Position Before Heating: Slide the sleeve into place before making the final connection if the connector or cable assembly prevents fitting it afterwards.
  • Apply Controlled Heat: Use a suitable heat gun and distribute heat evenly around the sleeve. Avoid excessive or concentrated heating.
  • Allow to Cool: Let the sleeve cool naturally and check that it has contracted evenly and remains securely positioned.

Important: A heat shrink sleeve provides insulation and physical protection, but it should not be treated as a substitute for a certified waterproof enclosure or a complete electrical safety system. Confirm the actual sleeve dimensions and application suitability before installation.
