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 (Meaning of XHH)?
答: NEC Designation.
X: Cross-Linked (XLPE).
HH: High Heat (90°C).
(Note: Lack of “W” indicates no Wet Location rating).
Q: XHH vs. XHHW-2?
答: Environmental Rating.
XHH: Dry & Damp Locations Only (90°C).
XHHW-2: Wet & Dry Locations (90°C). (Note: XHHW-2 is NOT rated for direct burial unless dual-rated USE-2).
Q: Max Temperature?
答: 90°C. (Restricted to Dry and Damp environments).
Q:Outdoor Suitability?
答: 不。. Not listed for Wet Locations. Must be installed in dry raceways protected from weather/moisture accumulation.
Q: XHH (Thermoset) vs. THHN (Thermoplastic)?
答: Insulation Physics.
XHH (XLPE): Chemical/Heat resistant; thicker insulation; no nylon jacket.
THHN (PVC): Vulnerable to heat deformation; requires nylon jacket for protection.
