4 AWG 1 Conductor Nickle Plated Copper Unshielded Fluoropolymer STS HT Skin-Effect Tracing Wire

Allowable Ampacity for 4 AWG 1 Conductor Nickle Plated Copper Unshielded Fluoropolymer STS HT Skin-Effect Tracing Wire: 100 Amps

About:

This type of wire is engineered for applications requiring high-temperature resistance and reliable performance. The nickel plating on copper enhances the wire's ability to withstand harsh conditions, including elevated temperatures and corrosive environments. The fluoropolymer insulation provides additional protection and high electrical reliability.

Also Known As:

• High-Temperature Nickel-Plated Copper Tracing Wire
• Fluoropolymer Insulated Tracing Wire
• Skin-Effect Heat Tracing Wire

Application:

• Area Classification: Hazardous and non-hazardous locations
• Traced surface type: Metal and Concrete
• Chemical resistance: Organic and aqueous inorganic chemicals and corrosives

Standards:

• ASTM and/or UL standards for high-temperature wiring
• Industry-specific standards for safety and performance
• Certifications for use in hazardous or corrosive environments

Construction:

• Conductor: The core is made of high-quality nickel-plated copper, offering excellent conductivity and resistance to oxidation at high temperatures.
• Insulation: A fluoropolymer material provides excellent electrical insulation, chemical resistance, and high-temperature operation capabilities.
• Skin-Effect: Utilizes skin effect heating technology, where AC current primarily flows along the outer surface of the conductor, enhancing efficiency in heat tracing applications.

Features:

• Custom engineered design, depending on the unique application type
• Safe and efficient in operation: fully grounded system with zero electrical potential on pipe surfaces, can be used in Class 1 Division 2 and Zone 2 hazardous areas
• Long circuit lengths (up to 15 miles/25 km), minimize operating and installation costs by reducing the required number of power supply points
• Advanced control systems with multiple temperature inputs to adequately monitor and control longline heat tracing
• Reliable during long life: entire circuit is encapsulated within rugged heat tubes and steel boxes
