Shrink-fit cable joints ease splicing process

The Elastimold Shrink-Fit cable joint from Thomas & Betts combines the convenience of pre-molded splicing with the versatility of cold-shrink methods into one, easy-to-install solution, says the company. Made of high-quality, molded EPDM elastomer, the Shrink-Fit cable joint features a single-piece body that can be quickly installed using a self-ejecting plastic support core, which can be easily removed by hand.

Thomas & Betts says the Shrink-Fit method uses no ripcords and no heat, making installation fast, simple and safe. “The Elastimold Shrink-Fit cable joint combines all the best elements of the various cable splicing methods into one product,” comments Chad Smith, vice president, product management and marketing, at Thomas & Betts.

The cable joint’s four-piece plastic support core reinforces the openings at both sides of the joint. According to the product's user instructions: To create a splice, insert the joint. After preparing and joining the cables together with a connector, cut the strapping bands on the elastomer Shrink-Fit joint, and the joint will contour itself around the splice as it pushes the pieces of the plastic core out of both sides. After the splice has been completed, cable neutrals can be re-connected easily over the body of the joint without having to use potentially dangerous spring clamps and without having to sacrifice any conductivity in the shield.

“Our customers were looking for a cost-effective alternative to pre-molded joints that featured the range-taking convenience of currently-available cold-shrink products, but without the use of ripcords or integral braids," concludes Smith. "We drew upon nearly 50 years of experience in designing molded power products, and responded with the first ever pre-molded, cold-shrinkable power cable joint.”

The Elastimold Shrink-Fit cable joint covers a range of cable sizes and can be used with either a standard aluminum or optional copper compression splice. A variety of optional kits are available for custom shielding and jacket restoration, based on individual needs and requirements.
