UL 3573 Silicone Wire 200°C 10kV High Voltage Fiberglass Braid Hook-Up Wire (Tinned Copper Conductor)

UL 3573 Silicone Wire is a high-temperature, high-voltage hook-up wire designed for demanding electrical and electronic applications that require superior thermal stability, dielectric strength, and long-term reliability. Featuring a stranded tinned copper conductor, silicone rubber insulation, and reinforced fiberglass braid with silicone jacket, this wire provides excellent flexibility, abrasion resistance, and insulation performance under extreme operating conditions.

Typical Specifications for UL 3573 style

While specific manufacturer data sheets should always be consulted, the UL 3573 style generally adheres to these specs:

• Temperature Rating: Typically rated for continuous use up to +200°C (and usually down to -60°C for cold flexibility).
• Voltage Rating: Most commonly rated at 600V or 1000V AC (depending on the specific manufacturer and wall thickness).
• Flammability: The silicone and fiberglass construction usually allows it to pass stringent flame tests (such as VW-1).

Common Applications

Given its unique combination of high heat tolerance, voltage handling, and mechanical durability, UL 3573 is frequently used in:

• Industrial Heating: Internal wiring for ovens, furnaces, and industrial heating elements.
• Motors and Generators: Lead wires that must withstand operating heat and vibration.
• High-Intensity Lighting: Wiring for floodlights or stadium lighting where temperatures soar.
• Heavy Machinery: Where wire might be routed around tight corners or subject to rubbing (abrasion) in hot environments.
