0.6/1kV Cold Shrink Cable Accessories (LSY Series)
Dry-shrink cold shrink cable accessories for 0.6/1kV power cables. The LSY series pre-expanded sleeves are held on a removable core during shipping and installation. Once the core is removed, the EPDM or silicone rubber recovers to provide a tight, seal-protected joint or termination without heat.

Applications by industry
- Underground 0.6/1kV power cable joints
- MV/LV cable terminations for switchgear
- Street lighting and building service cable connections
- Moisture-sealed terminations in buried or damp installations
- Industrial motor power cable protection
- Renewable energy string cable joints (PV systems)
Why heat-shrink tubing for this application
Heat-shrink tubing provides environmental sealing and mechanical protection when shrunk over wire harnesses and connector assemblies. Recovery temperature determines application method.
Cannot be stretched back once recovered; UV degradation if exposed without additional protection. Not for continuous high-load mechanical situations.
Standards: ASTM D2048, IEC 60228, UL 224 (flame retardant), RoHS and REACH compliant.
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 shrink ratio is available?
Ratios from 2:1 to 4:1 depending on material and wall. Dual-wall adhesive-lined versions provide environmental sealing.
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.
