Silicone Rubber Wire
Flexible high-temperature wire, -60°C to +200°C -- for appliances, lighting, motor leads, and industrial automation.
What Is Silicone Rubber Wire?
Silicone rubber wire uses a silicone elastomer insulation instead of PVC or rubber, giving it two properties that don't usually come together: it stays flexible down to -60°C while also withstanding continuous operation up to 200°C. That combination makes it the standard choice anywhere a wire needs to keep bending or flexing in a hot environment -- appliance internal wiring, lighting fixtures, motor leads, and industrial automation -- rather than stiffening and cracking the way PVC insulation does above roughly 105°C.
Choosing the Right Silicone Wire Construction
Voltage class is the first specification decision across this family. The 300-600V constructions (JG, AGR, UL AWM 3132/3135, AGG) cover the overwhelming majority of appliance, lighting, and general industrial wiring. JHXG 1140V is the outlier -- a heavy-wall, high-voltage-grade construction built specifically for mining equipment and industrial motors operating at up to 1140V, where standard silicone wire's insulation thickness isn't sufficient for the voltage stress.
Standard vs. fiberglass-braided silicone wire is the second decision, and it comes down to mechanical exposure. Plain silicone constructions (JG, AGR, AGG) suit wiring that's protected inside an enclosure or conduit. JGG adds a fiberglass overbraid on top of the same silicone insulation, trading a small amount of flexibility for meaningfully better abrasion and cut-through resistance -- worth the upgrade anywhere the wire runs exposed near moving parts or sharp edges rather than fully enclosed.
-60°C to +200°C
Stays flexible across an unusually wide temperature range -- won't stiffen and crack like PVC above 105°C.
Up to 1140V
JHXG 1140V construction covers heavy-industry and mining-equipment voltage requirements beyond standard 300-600V wire.
UL / VDE / RoHS
UL AWM 3132/3135, UL3512, VDE, and RoHS compliant constructions across the family.

Silicone Rubber Wire FAQ
What temperature range can silicone rubber wire handle?
Standard silicone rubber wire in this family stays flexible from -60°C up to +200°C continuous operation, which is a wider working range than PVC (roughly 0°C to 105°C) or standard rubber insulation.
When do I need JHXG 1140V instead of a standard 600V construction?
JHXG 1140V is a heavy-wall, high-voltage-grade silicone construction for mining equipment and industrial motors operating up to 1140V. For general appliance, lighting, and industrial wiring at 300-600V, the standard JG, AGR, AGG, or UL AWM constructions are the correct fit.
What's the difference between JG and JGG?
JGG is JG with an added fiberglass overbraid for better abrasion and mechanical protection. Choose JGG for wiring that runs exposed near moving parts or sharp edges; JG is sufficient for wiring protected inside an enclosure or conduit.
Is silicone rubber wire flame retardant?
Yes -- silicone rubber insulation is inherently flame retardant and self-extinguishing, which is part of why this family is standard in appliance and lighting applications subject to UL and RoHS compliance requirements.
