Single Conductor Multi Listed Flexible Wire
THHW / TEW / MTW / AWM / BC-5W2 / SAE TYPE SGT
Polar Wire's Single Conductor Multi Listed Flexible Wire is a Class K Flexing Service Wire made with 30 gauge stranding for superior flexibility. It features excellent oil, heat, acid, and moisture resistance. This wire is constructed of soft annealed bare copper to ASTM Specification B172, and insulated with an extra-flexible extruded, high dielectric PVC jacket. It can be used in NEC Article 310 and NFPA Standard 79 applications, in temperatures as high as 105°C.

Multi Listed Flexible Wire carries multiple ratings and certifications:
Flexible Building Wire
An excellent oil, heat, acid, and moisture resistance Class K Flexing Service Wire constructed with 30 AWG stranding for superior flexibility. Conductors are soft annealed 100% copper with no aluminum, constructed to ASTM Specification B172. Extra-flexible extruded, high dielectric PVC insulation.
- Rated for -40°F to 221°F (-40°C to 105°C)
- UL Listed and CSA Certified
Fine Strand Battery Cable
More flexible than standard battery cable even in very cold temperatures. Cables made with Multi-Listed Flexible Wire withstand persistant vibration and flexing for reliability and longevity. Ideal for battery and starter cables, ground cables, and jumper cables.
- Fine strand annealed 100% copper conductor with a tough oil, heat, acid, and water resistant PVC jacket
- Meets and exceeds SAE standards, marine ratings
Flexible Welding Cable
30 AWG Class K fine stranded annealed copper conductors provide excellent conductivity and flexibility, reducing operator fatigue and improving efficiency. The tough, extra-flexible, high dielectric PVC jacket resists abrasion, oils, acids, heat, flame, and moisture, and performs reliably in severe cold temperatures and high heat conditions.
- Rated for -40°F to 221°F (-40°C to 105°C)
- Meets UL VW-1 and CSA FT1 flame test requirements.
Single Conductor BC-5W2 Marine Boat Cable
BC-5W2 Boat Cable rated for 600 Volts. This flexible wire resists vibration and flexing fatigue, withstands salt water, oil, and fuel exposure, and stays pliable in cold down to -40°F to 221°F (-40°C to 105°C). Its 30 AWG Class K fine 100% copper stranding and highly flexible jacket eases installation in the constricted spaces and tight corners typical of boats.
- Meets or exceeds ABYC standards
- Meets UL VW-1 and CSA FT1 flame test requirements
