3M 3570G-N – Frequently Asked Questions

1) What size cable does the 3M Scotchcast 3570G-N sealing pack fit?
The 3570G-N connector sealing pack is sized for conductors from 35mm2 up to 95mm2, with cable insulation outside diameters between 0.64 and 1.01 inch (16.3 to 25.7 mm). Measure over the insulation, not the jacket, before you order. If your cable insulation falls outside that OD window, the mold body won't close correctly around the connection and you need a different size pack.
2) Can I use the 3M 3570G-N on XLPE or EPR underground feeder cable?
EPR, XLPE, XLP and other solid dielectric cables are all within scope for the 3570G-N. It works on armored and non-armored shielded cable, and it is rated for indoor or outdoor use, which is what makes it usable on direct-buried and vault work. The pack is built around a 3-conductor connection.
3) How long do I have to work with the resin after mixing the 3570G-N?
Gel time on the 3570G-N epoxy is 8 to 12 minutes at 73F (23C), so plan on pouring immediately after mixing and having the connection already made up and positioned. It cures at room temperature, no heat or torch needed. In cold weather the gel time stretches out, and in hot weather it shortens, so mix one pack at a time rather than staging several.
4) What voltage is the 3M 3570G-N connector sealing pack rated for?
The 3570G-N is a medium voltage product with a stated product voltage of 0 to 600 kV and a dielectric strength of 435 V/mil in the cured resin. Dielectric strength is the property that actually governs the insulation performance of the casting, so it is the number to check against your engineer's spec.
5) Is the 3M Scotchcast 3570G-N a flexible or a hard splice once it cures?
It cures rigid. The epoxy reaches 60 Shore D hardness with 1779 psi tensile strength and 57 percent elongation, so the finished body is a hard block, not a rubbery one. That matters for placement: put it where the cable is supported and not being flexed, because a rigid casting will not follow repeated cable movement the way a gel or rubber splice does.
6) Does the 3570G-N seal the whole splice or just the connector?
It seals the connector itself. The 3570G-N is a connector sealing pack, built to protect electrical spring connectors from water, dust and soil at the connection point. Typical splice length in the application is 52.0 inches (1320 mm), so allow that much working room in the vault, handhole or trench for the full made-up joint even though the resin body covers only the connection.
7) Do I need a mold or extra kit parts to use the 3M 3570G-N resin pack?
The 3570G-N ships as a self-contained sealing pack for a wire connector, so the resin comes packaged for pour with no separate mixing pot. The whole unit weighs 0.4 lb and measures 5.75 inches by 1.75 inches, which tells you how much space the pack occupies over the connection. Anything you need beyond that is the connector and the cable prep itself, not part of the resin pack.
8) Is 3M Scotchcast resin flame retardant for indoor vault and building work?
The epoxy resin in the 3570G-N is flame retardant, which is why it gets used inside buildings and equipment rooms as well as in underground and outdoor runs. It is a black, liquid two-part epoxy in the pack and cures in place.
