Tổng quan
YOCL Điện 4:1 Zero-Halogen Single-Wall Heat Shrink Tubing provides electrical insulation, cable protection and component covering where a wide recovery range is required. It is manufactured from irradiated cross-linked modified polyolefin with zero-halogen and low-smoke characteristics.
The 4:1 shrink ratio allows the tubing to pass over a connector, terminal or cable joint before recovering around a smaller cable diameter. The thin single wall has no internal adhesive layer. Seven sizes are available from 8/2 mm to 25/6.25 mm, with an operating temperature up to 125°C.
Tính năng
- 4:1 recovery range: Accommodates connectors, terminals and changes in cable diameter.
- Zero-halogen formulation: Provides a material option for applications with halogen-content requirements.
- Low-smoke characteristics: Supports material selection for electrical and electronic equipment.
- Thin single wall: Provides a compact, flexible insulating cover.
- Modified polyolefin construction: Uses irradiation cross-linking.
- Electrical and mechanical properties: Rated voltage options, insulation test values and mechanical properties are listed below.

I.D. means internal diameter. All diameters, wall thicknesses and tolerances are in millimetres. The ≥ values specify minimum supplied internal diameters; the ≤ values specify maximum internal diameters after full recovery. Supplied and recovered dimensions apply to the same size row.
Selection Guide
Select a supplied internal diameter that can pass over the largest cable connector, terminal or component. Check the maximum recovered internal diameter against the smaller area to be covered, together with the recovered wall thickness.
For example, the 12.0/3.0 mm option has a supplied I.D. of at least 12.0 mm and a fully recovered I.D. of no more than 3.0 mm. Its supplied wall thickness is 0.25 ± 0.05 mm, and its recovered wall thickness is 1.00 ± 0.15 mm.
Specify the required 300 V or 600 V rated option with the selected tubing size. Use the dimensions in the table to assess fit and the available installation space.
Ứng dụng
- Automotive wire harnesses and electrical wiring.
- Electrical connector, terminal and splice covering.
- Wire and cable repair, joints and diameter transitions.
- Electrical and electronic component insulation.
Installation Notes
- Select a tubing size that can pass over the largest cable, terminal or component.
- Cut it to the required length and slide it into position.
- Apply controlled heat evenly around the tubing.
- Move the heat source continuously to promote uniform recovery.
- Continue heating until the tubing has recovered around the component.
- Allow it to cool before handling.
Avoid overheating or concentrating heat at one location.
