Cable sleeve DELOCK 19029, polyester, orange, operating temp -40–150°C, length 1000 mm

Delock 19029 is a flat, double-layer cable sleeve designed to protect cables and high-voltage copper busbars from abrasion and mechanical damage. Made from polyester and finished in bright orange, the sleeve combines robust protection with flexibility and compact dimensions (40 x 16 mm) for space-saving cable routing. An integrated wear indicator signals when the sleeve has been worn through and requires inspection or replacement.

Advantages

The double-layer construction increases mechanical strength while maintaining flexibility for straightforward installation. The bright orange colour improves visibility during inspection and maintenance. A built-in wear warning makes it possible to detect heavy abrasion early and replace the sleeve before the underlying cable is exposed. The sleeve is resistant to high temperatures, impact and abrasion and meets recognized test standards for flammability and environmental ageing.

Suitable for

• Protection of electrical cables in vehicles, machinery and industrial installations
• Covering high-voltage copper busbars to prevent abrasion and short circuits
• Applications requiring visible cable marking for safety or maintenance
• Space-limited cable routing where a flat profile (40 x 16 mm) is advantageous

When it may not be suitable

This sleeve is not intended as the sole insulation for live conductors; it is a protective cover and should be used together with appropriate electrical insulation measures where required. It may not be suitable where continuous mechanical exposure exceeds the validated abrasion or impact limits, or where additional chemical resistance beyond polyester's characteristics is necessary.

How to use

Slide the sleeve over the cable or busbar along its length. For busbars or multi-cable runs, position the flat side to match the available space and secure the sleeve ends as required with appropriate clamps or heat-resistant ties. Regularly inspect the sleeve for wear; when the orange layer or the integrated wear indicator becomes visible, check the underlying cable and replace the sleeve if necessary to maintain protection.

What to consider before purchase

• Confirm the flat cross-section 40 x 16 mm fits the cable bundle or busbar with sufficient clearance
• Verify the operating temperature range (-40 °C to 150 °C) suits the intended environment
• Assess whether polyester chemical compatibility is adequate for exposure to oils, fuels or solvents
• Decide if a 1000 mm length is appropriate or if multiple lengths/segments are required

Recommendations

Install the sleeve with the wear indicator facing outward for visual checks. Replace the sleeve promptly when the indicator shows wear to avoid exposure of the underlying conductors. Use additional insulation or protective measures where electrical insulation or greater chemical resistance is required.
