⚡ Protect What Powers Your Business.

From transformers to electronic modules, 3M™ Scotchcast™ 8 Electrical Resin delivers reliable insulation, moisture resistance, and long-lasting protection for critical electrical applications.

Once upon a time, 3M introduced a vinyl electrical tape. That was in 1946 and at the time 3M revolutionised the role of electrical tapes for maintenance and repair jobs. 

Since then the use of conventional electrical tapes has declined as modern product advances, such as 3M Cold Shrink Tubes, have replaced traditional taped solutions. 

Electricians are unlikely to consider "old-school" taping skills to be an important element in the engineers skill-set of today. However, there are several good reasons to master the craft. When quick on the spot repairs are required and other products are simply not available, 3M Scotch Electrical Tapes can be real "day-savers". 

Today 3M Electrical Tapes still offer long-term performance, excellent adhesion, chemical resistance and temperature performance - a smooth unwind from the roll can provide "quick-fix" and simple solutions to electrical insulation tasks. 

The primary 3M Scotch tapes used in electrical applications are vinyl, rubber, mastic, and corrosion protection. The function of moisture-sealing tapes such as vinyl, rubber, and mastic products is to exclude moisture from the insulation assembly and provide electrical insulation. One of these tapes — or alternatively a 3M mastic pad — generally forms the second layer of the insulation assembly. 

Rubber, mastic, and filler tapes are also used to pad the underlying surface by covering sharp edges. 

3M Scotchcast Cable Joints – Selection Factors, Specification Considerations & Application Notes

Why Gamble With Your Power Supply By Installing Underspecified Cable Joints?

A Failed Cable Joint.

The purpose of any cable joint is to remove damaged sections of cable and re-instate the electrical performance of the jointed cable as closely as possible to the original manufactured condition.

The specification, selection and installation of Low Voltage Resin Cable Joints vary according to industry. So, without a universal methodology the selection factors are specific to the cable and industry.

Several key factors include : cable function, cable reliability and consequential loss due to outage or downtime.

Standard resin cable joints are often inadvertently installed forming weak links in many industrial cable networks. Most recently we “loud-halered” the catastrophic dangers of cutting the cable joint cost-corner to the offshore industry.
