- Motor cable terminations and sealing
- Cable lug and gland sealing tails
Why heat-shrink polyolefin kits for this application
Heat-shrink accessory kits give a field-applied, moisture-tight termination and joint system that matches the cable's insulation class when the right size and voltage kit is selected.
Sizing and surface prep (clean, dry, rolled edges) dominate performance; a mismatched kit fails at the interface, not the sleeve. Verify against cable OD and kV class.
Standards: IEC 60502 (MV cables), CENELEC HD 629, IEEE 48.
Feature and remaining-wall review
Cut to length before installation; dual-wall adhesive lined requires controlled heat profile for proper flow. Review feature depth, edge distance and remaining wall against critical geometries. Capability is confirmed on your drawing, not from a blanket tolerance.
Inspection and traceability
We state the control plan with you. Batch traceability links raw material lot to finished part.
- First-article inspection (FAI) per your plan
- In-process dimensional checks at every station
- Batch certificate of conformance (COA) supplied on request
- Lot traceability to incoming material certificate
- Dielectric strength and insulation resistance testing available on request

Common questions
What recovery temperature is needed?
Standard polyolefin recovers at 90–135 °C. PTFE at 300–400 °C. Match the recovery temperature to your assembly heat profile.
Is it RoHS and REACH compliant?
Yes. All standard grades comply with RoHS 2011/65/EU and REACH 1907/2006. Certificates supplied per batch.
Can heat-shrink be printed?
Yes — identification bands, logos and warnings printed before or after shrink. Ask for print area and ink compatibility.
What wire sizes does it fit?
ID from 0.2 mm to 200 mm flat wall, 3 mm to 300 mm dual-wall. Refer to the sizing chart on the product page.
Do you build kits to a cable list?
ID from 0.2 mm to 200 mm flat wall, 3 mm to 300 mm dual-wall. Refer to the sizing chart on the product page.
