Feeder wire is often selected long before the cable reaches a site. For a buyer comparing XHHW-2 manufacturers in Vietnam, the useful question is how the conductor, insulation and installation requirements fit together. XLPE construction gives this wire family a different material system from PVC-and-nylon THHN.
Inside the cable
The copper reference consists of a stranded copper conductor surrounded by thermoset cross-linked polyethylene insulation. Cross-linking creates a polymer network rather than an ordinary thermoplastic layer. The representative single conductor has no separate multicore jacket, metallic screen or armour. Copper and aluminium constructions both exist in the industry; conductor material must be stated rather than inferred from the designation.
Where it is used
Typical enquiries concern power services, feeders and branch circuits in conduit and other recognized wiring systems. It is relevant to commercial distribution, industrial buildings and infrastructure buyers who need defined power-wire sizes. Cable tray, open wiring and sunlight exposure require review against the exact construction, conductor size, markings and installation conditions.
Ratings and selection points
XHHW-2 is a 90°C wet/dry insulation category, but the final circuit rating still depends on the full installation. Voltage ratings can vary between products and sizes. The Southwire reference distinguishes XHHW-2 ratings from its Canadian RW90 marking; a dual-rated wire must be read under the designation being used. Do not transfer a 1,000 V claim across an entire catalogue or treat XLPE as proof of direct-burial approval.
A clearer factory RFQ
A feeder package should state conductor material, AWG or kcmil, conductor class, colour identification and required voltage. Include route type, expected reel lengths and quantity per size. Ask the factory to confirm nominal outside diameter and handling limits so the buyer can check raceway space and drum handling before shipment.
Compare the TGS XHHW-2 configurations for the available reference size tables. State the required conductor resistance, nominal dimensions, test documents and marking for the exact order. Reference tables and illustrations guide the enquiry; the agreed drawing and approved specification define production.
Manufacturing in Vietnam with TGS
TGS Cable Industrial is a large manufacturing group producing wire and cable in Vietnam. The group has served Costco, Walmart, Target and many other customers for more than five years. That company-wide experience informs our work with importers, distributors and retail supply programmes. For your XHHW-2 enquiry, our factory team reviews the construction, destination requirements, quantities and packing before confirming the order.
Explore our Vietnam factory production capability, or send your cable specification to discuss a factory quotation. Product approvals and customer-specific requirements are reviewed for the selected construction and programme.
Frequently asked questions
How does XHHW-2 differ from THHN?
The usual XHHW-2 construction uses thermoset XLPE; typical THHN uses PVC insulation with nylon covering. Compare finished dimensions, required ratings and installation needs for the selected products.
Does XHHW-2 always mean 1,000 V?
No. Confirm the voltage on the actual product documentation and marking. Size, construction and any separate RW90 rating must be checked individually.
Technical references
Manufacturer references explain the representative cable family and construction. They do not certify a TGS product. The agreed order drawing, product marking and applicable approval documents define the supplied cable.
