Tape Repairs for Damaged Cables

Safe and reliable electricity distribution depends upon the integrity of power cables and the monitoring and maintenance of cable condition to ensure service is not disrupted by cable failure – the early warning indication of potential power problems is the condition of the Cable Sheath.

3M Electrical and Scotch brand tapes provide high specification and performance repairs to damaged cable sheaths and jackets for power systems, 600V to 66kV – this can include minor sheath nicks and more substantial deeper damages caused during the transportation, cable pulling or operational service of the cable circuit.

Scotch Electrical tape repairs from 3M provide durable sheath re-instatement to LV MV HV cables located in underground or outdoor locations providing excellent protection against moisture and contaminant penetration into the cable construction and consequently compromising cable circuit integrity and power system uptime.

• Convenient tape solutions for service vans with reduced inventory, cost and disruption
• Versatile field repairs from the roll with range-take for diameter cables
• Ideal for repair of stress cracks and splits caused by exceeding cable bending radius
• Quick and easy tape repairs requiring no flames, heating or gas torch for safe use in confined spaces and potentially explosive atmospheres with hazardous areas Zone 1/2
• Flexibility and fast repair with excellent cable sheath adhesion

Temporary & Permanent Repair of Field Damaged

Low & High Voltage Cable Using Electrical Tapes

Damage Level 1	Damage Level 2	Damage Level 3
Minor damages. Surface damages like scratches and grooves from sharp edges.	More substantial damages with cable cores intact. Cuts and breakouts of the cable jacket.	A new cable splice is required. Severe damages with damages cable cores. Punctures and deep damages affecting the inner layers of the cable. Further detection of the cable is necessary.

Task – Repair for Minor Damage Cables 

For repairing cable damage like scratches and grooves from sharp edges:

• Clean the cable surface with a solvent and sandpaper – use 3M™ Cable Preparation Kit CC-3 or Scotch® 1626 Degreasing and Cleaners
• Half-lap Scotch® Cable Jacket Repair Tape 2234 over the damaged jacket area
• Overwrap each end with Scotch® Super 33+™ Vinyl Tape. This tape will add radial pressure to ensure optimum adhesion and sealing

Task – Repair for Substantial Damage Cables 

When dealing with more significant damage where a portion of the cable jacket is torn, first check if the inner layers of the cable are undamaged:

• Remove the torn and damaged edges of the cable jacket
• Clean the cable surface with a solvent and sandpaper – use 3M™ Cable Preparation kit CC-3 or Scotch® 1626 Degreasing & Cleaning Spray
• Fill and seal voids with 3M™ Scotchfil™ Electrical Insulation Putty
• Overwrap the whole repair length with Scotch® Cable Jacket Repair Tape 2234

This range of GORE-TEX PYRAD Waterproof Arc Flash Protection is Class 2 rated, Arc Flash and Fire resistant and brings a level of comfort and protection where workers can focus on the job at hand and work for long periods of time outdoors and in tough conditions.

Reaching temperatures of up to 35,000°F—four times hotter than the surface of the sun and producing a sound louder than a gunshot, an arc flash is a terrifying danger that any workplace can be exposed to every day.

Add in the effects of wet weather and other extreme conditions that can impair workers’ ability to perform, and the risk of a life-threatening arc flash incident is heightened.

ProGARM and GORE have joined together to bring the Arc flash protection line to keep wearers warm, dry, and safe.

Arc Rated GORE-TEX PYRAD fabric stays lightweight and comfortable even when wet. They remain up to 20% lighter when wet or dry than other arc protection category 3 garments, making them feel less bulky to wear. Wearing the right protective gear in foul weather can make all the difference in job performance.

Fabric that avoids a build-up of heat

GORE-TEX fabrics feature durable waterproof and windproof protection with high breathability. The fabric is engineered so that sweat vapour can escape to avoid a build-up of heat and perspiration, and it can also easily withstand high water pressure.

Unlike any other arc flash PPE using the same fabric,

As the only UK manufacturer specialising 100% in arc flash and flame resistant PPE, ProGARM continuously invests in industry-leading research and testing to keep on top of developments in new manufacturing and design techniques, better fabrics, and safer materials.

Pioneering design and attention to detail mean ProGARM’s arc flash PPE is engineered with unique differences to maximise safety and comfort.

Every single element is arc flash and flame resistant, right down to the stitching threads and increasing safety through layers.

Garments are designed to be as comfortable and practical to wear as possible, regardless of gender. ProGARM has developed one of the widest ranges of female-specific arc flash garments on the market, tailoring for different body proportions and for smaller details such as the wider range of motion of female joints—something ProGARM will continue with their new GORE range, which will include jackets, trousers, and coveralls.

Maximising safety and comfort

Maximum comfort with the higher protection from arc flash, so workers remain safe no matter the challenge, or the weather.

Safely fitting workwear for male and female body shapes. High levels of customer service customers have come to depend on. These are just some of the benefits companies and workers can expect to see as ProGARM and GORE unlock new levels of protection in their new range of arc flash PPE.
