Everything in One Box: The MV Cable Clean & Seal Kit from Utility Power Supply Company

When a crew heads out to splice or terminate medium-voltage cable, the last thing they need is a scramble for supplies. Did someone grab the right cleaner? Are the wipes lint-free? Is there enough sealant on the truck? The MV Cable Clean & Seal Kit — offered by Utility Power Supply Company and powered by Polywater® — eliminates all of that uncertainty with a single, job-ready solution.

One Kit, Complete Prep

Medium-voltage cable preparation is a multi-step process, and each step matters. Residue from semicon shield, dielectric oils, silicone greases, or filling compounds left on insulation surfaces can cause tracking failure and compromise splice integrity down the road. The Clean & Seal Kit bundles the cleaning and sealing essentials needed to do the job right — all in one package.

At the heart of the kit is Polywater® Type RP™, a fast-evaporating cable cleaner purpose-built for HV/MV work. It effectively removes semi-conducting cable shield, dielectric oils, silicone greases, filling gels, and transformer oils commonly encountered during electrical construction and maintenance. Critically, it evaporates quickly without the health and safety issues associated with other volatile cable cleaners. ‍

The kit uses Pel-Pac™ pre-saturated wipes — a format that field crews consistently prefer. Pre-packaged wipes ensure the use of a lint-free towel, limit solvent exposure, eliminate waste, and properly prep the cable. They fit easily into tool bags, nose bags, and splicer tool buckets, and they remove the guesswork of how much solvent to apply — important because over-application can cause pooling and tracking failure.

Performance You Can Count On

This isn't just a convenience product — it's engineered to meet utility-grade standards. Type RP delivers a dielectric strength greater than 56 kV, meeting IEEE 1493, and is approved by medium-voltage cable manufacturers. That kind of third-party validation matters when you're working on energized infrastructure.

On the sealing side, the kit incorporates Polywater's proven conduit sealing technology to protect completed work from moisture, gas, and environmental intrusion — safeguarding against moisture, gas, and contaminant intrusion through conduit openings and fittings to maintain cable integrity and system safety.

Why It Matters for Utility Crews

Time in the field is expensive, and errors in cable prep are even more so. A kit format means everything needed for a proper clean-and-seal sequence is accounted for before the job starts. No substitutions, no missing components, no shortcuts that come back to bite.

For utilities and contractors in the Northeast — the market Powertech Associates has served for decades — that kind of operational reliability is exactly what's needed. Whether it's a planned splice in a manhole or an emergency termination in the field, having the right products in hand from the start is the difference between a confident crew and a compromised job.
