產品說明
XHHW : Product Description and Specifications
Type XHHW designates a single-conductor 600V building wire for installation in recognized raceways. Featuring thermoset Cross-Linked Polyethylene (XLPE) insulation over annealed copper or aluminum conductors, this specification is rated for continuous operation at 90°C in Dry locations 和 75°C in Wet locations. The integral XLPE insulation provides required mechanical resistance to abrasion, heat, and chemicals without the inclusion of a nylon jacket, complying with UL 44 標準。.

優點
XHHW : Benefits and Features
Superior Durability: The XLPE insulation is physically tougher and more resistant to abrasion and crushing than standard PVC (THHN) wire.
抗化學性: Excellent resistance to acids, alkalis, oils, and industrial chemicals.
耐濕性: Designed to withstand damp environments and moisture ingress (up to 75°C).
阻燃劑: Formulated to resist spreading fire; XLPE typically produces less toxic smoke than PVC during combustion.
Installation Efficiency: The surface is naturally smooth and robust, often making it easier to pull through conduits without damage compared to nylon-jacketed wires.
No Creep/Flow: Being a thermoset material, the insulation will not melt or flow under overload conditions like thermoplastic (PVC) materials might.

UL電纜的生產流程
JOCA produces UL wires using a fully automated workflow. The cycle synchronizes copper drawing and stranding with precise PVC or XLPE extrusion. Instead of waiting for post-production checks, we employ continuous inline monitoring—using laser diameter gauges and spark testers to catch defects instantly. For multi-core variants, the line handles cabling, shielding, and jacketing to exact specifications. Before shipping, every batch faces final electrical and mechanical inspections to verify full compliance with UL standards.

Q: Nomenclature Definition?
答: NEC Designation.
X: Cross-Linked (XLPE).
HH: High Heat (90°C Dry).
W: Water Resistant.
Q: XHHW vs. XHHW-2?
答: Wet Temperature Limit.
XHHW: 75°C (Wet) / 90°C (Dry).
XHHW-2: 90°C (Wet & Dry).
Q: Jacket Construction (vs. THHN)?
答: Non-Jacketed. Features integral Thermoset XLPE insulation only. No outer nylon sheath required (unlike Thermoplastic THHN).
Q:電壓等級?
答: 600V. General purpose NEC power distribution.
Q:濕位置能力?
答: Restricted. Approved for Wet Locations, but derated to 75°C maximum operation. (90°C permitted in Dry locations only).
Q: XLPE (XHHW) vs. PVC (THHN)?
答: Material Properties.
Thermoset (XHHW): Superior dielectric constant, chemical resistance, and overload stability.
Thermoplastic (THHN): Lower cost, thinner OD.
Q:抗日光能力?
答: Specification Dependent. Not inherent to standard XHHW. Must be explicitly listed and marked “抗陽光” for outdoor use.
Q : Conductor Availability?
答: Standard Options.
銅: Solid or Stranded (Soft Annealed).
鋁: AA-8000 Series Alloy (Stranded).
