XLPE Building Wire Insulation
XHHW-2 uses cross-linked insulation for feeder and branch circuits requiring wet and dry location review.
XHHW-2 Wire
XHHW-2 Wire for building wire and fixed electrical installation routes.
XHHW-2 Wire is selected for building and feeder circuits requiring XLPE insulation performance and wet/dry location review.
Product Overview
XHHW-2 Wire should be selected according to the actual project route, not by product name alone. Before quotation, review wire type, conductor material, temperature rating, wet/dry location rating and local electrical code route. Datasheet wording, compliance documents and final supply notes should stay aligned with the selected standard and installation conditions.
Applications
- building feeders and branch circuits requiring XLPE insulation performance
- conduit or raceway routes where wet/dry location rating must be reviewed
- commercial and industrial electrical systems using UL 44 style wire selection
- projects comparing THHN/THWN-2 and XHHW-2 according to insulation route
Construction
copper or aluminum conductor with insulation and jacket system according to building wire type. Final conductor size, temperature rating, wet/dry location rating and wire type, temperature rating and installation route should follow the selected code route.
Marking on Cable
FARWALK CABLE – XHHW-2 Wire – [standard] – [size] – [rating] – [year] – [meter mark]
Cable Identification
- Insulation color, conductor identification and printed marking can be matched to the requested building wire type.
- Wire type, conductor size and temperature rating should remain clear in product marking when required.
Standards
- UL 83
- UL 44
- UL 854
- ASTM B800 / B801 where applicable
Main Features
Conduit and Raceway Use
Suitable for building wiring routes installed in conduit, raceway or approved cable assemblies.
Copper or Aluminum Options
For XHHW-2 Wire, conductor material and size should be selected according to ampacity, voltage drop and local electrical code.
Product Selection Guide
Wire Type
Confirm THHN/THWN-2, XHHW-2, THW, TFFN/TFN, SER or SEU before selecting conductor and insulation.
Local Code Route
Building wire must follow the destination market electrical code and approved installation method.
Wet / Dry Location
Review insulation rating, jacket type and temperature class according to conduit, raceway or service entrance use.
Conductor Material
Choose copper, aluminum or 8000-series alloy according to ampacity, voltage drop, termination and budget.
