This inside-rubber GS grade inverts the standard SRS (inside-fiber) construction: extruded silicone rubber inside, braided fiberglass outside, finished with silicone resin. It holds 7000 V average withstand with a notably high 6000 V minimum individual — the tightest avg/min gap in the range, and mechanical protection from the outer glass braid.
| Test standard | UL 1441 construction |
| Operating temperature | −60 °C to +200 °C (−76 ~ 392 °F) |
| Dielectric (avg. withstand) | 7000 V |
| Dielectric (min. individual) | 6000 V |
| UL recognition | UL 1441, File E233804 (Model GS-WCW-70) |
| Flame rating | UL VW-1 |
