Standard Silicone Rubber Insulated High Temperature Wire – AGR and AGRP Series
The AGR and AGRP series are standard Chinese designation codes for single-conductor silicone rubber insulated high temperature wire — AGR for 300V rated and AGRP for 600V rated construction. Both series use extruded silicone rubber (VMQ) insulation over a copper conductor, providing a continuous operating temperature of 200°C with a –60°C lower limit, making them suitable for internal wiring of heat-generating appliances, motor lead connections, and industrial equipment where standard PVC wire would exceed its thermal limits.
In UL AWM terms, AGR/AGRP wire corresponds to Styles 3071 and 3135 respectively — the two most common UL silicone rubber AWM styles for appliance internal wiring. UL AWM Style 3071 (200°C, 600V, 18–13 AWG, 30 mils SR insulation with fiberglass braid) and Style 3135 (200°C, 600V, 26–12 AWG, 30 mils SR insulation, no braid) are both produced at our Yangzhou facility under UL Follow-Up Service File No. E333030.

Common Applications
Household appliance internal wiring
AGR and AGRP wire are the most commonly used silicone rubber wire types in Chinese household appliance manufacturing — used for connections between heating elements and thermostats, between motor terminals and control boards, and for any internal wiring run where the wire passes through or near a heat-generating component. The 200°C rating provides adequate margin above the 85°C to 130°C temperatures typically encountered in appliance hot zones.
Motor lead connections
The AGR series (with fiberglass braid outer covering) is used as motor lead wire — the short connection between the motor winding terminal and the motor terminal box — where the wire must be rated for the Class F (155°C) or Class H (180°C) thermal environment of the motor winding and the mechanical protection of the braid is required to withstand handling during motor assembly.
Industrial heating equipment
Both AGR and AGRP series are used for internal wiring of electric heaters, industrial dryers, infrared heating panels, and heat-sealing equipment where the internal ambient temperature is in the 100°C to 180°C range — above the practical limit of 105°C-grade PVC wire.
Other applications
- Lighting fixture internal wiring in high-ambient-temperature environments
- Transformer and inductor lead connections in enclosed equipment
- Electric vehicle on-board charger and BMS internal wiring
- Commercial kitchen equipment internal wiring
