4 AWG 1 Conductor Tinned copper Unshielded Polyolefin 5000V STS MT Skin-Effect Tracing Wire

Allowable Ampacity for 4 AWG 1 Conductor Tinned copper Unshielded Polyolefin 5000V STS MT Skin-Effect Tracing Wire: 100 Amps

About:

This wire is designed for power distribution applications where skin-effect heating is utilized. The tinned copper conductor ensures excellent conductivity and corrosion resistance. The unshielded design is typically sufficient for its intended uses, where electromagnetic interference is not a primary concern. Its 5000V rating indicates high voltage endurance, making it suitable for robust applications.

Also Known As:

• Skin-effect heat tracing wire
• High voltage tracing wire
• Tinned copper polyolefin 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 B33 for tinned copper conductors.
• UL standards related to electrical wire and cable specifications.
• Relevant IEEE standards for skin-effect heat tracing systems.

Construction:

• Conductor: Tinned copper, offering superior corrosion resistance and conductivity.
• Insulation: Polyolefin insulation provides excellent electrical insulation properties and resistance to various chemicals and environmental conditions.
• Voltage Rating: Designed to withstand up to 5000 volts, indicating its suitability for high voltage applications.
• Skin-Effect: Utilizes the skin effect for efficient heating, where alternating current predominantly flows near the surface of the conductor, enhancing its heating capability.
