UL 44 XLPE Switchboard Wire
JZD American Standard SIS Cable is a single-conductor, 600V switchboard wire built with flexible stranded tinned copper and XLPE (cross-linked polyethylene) thermoset insulation. Manufactured to UL 44 / UL 3173 standards with VW-1 flame rating, it delivers a 90°C temperature rating in dry, damp, and wet locations. From 18 AWG to 4/0 AWG, this UL SIS wire is engineered for the internal wiring of switchboards, panelboards, and industrial control panels where heat resistance, flexibility, and long-term reliability matter most.
Key Benefits
- Superior Thermal Stability — XLPE thermoset insulation maintains integrity at 90°C continuous, resisting melt or deformation during overloads.
- VW-1 Flame Retardant — Passes stringent vertical flame tests, preventing fire propagation inside dense enclosures.
- Resists Oil, Moisture & Chemicals — Performs reliably in harsh industrial environments, including near cooling systems and in damp locations.
- Ultra-Flexible for Tight Spaces — Stranded tinned copper conductor routes easily through crowded switchboards and hinged panel doors without fatigue.
- UL & RoHS Compliant — Certified under UL 44 / UL 3173 and RoHS 2.0, ensuring global market acceptance and hassle-free project approvals.
- Precise Circuit Identification — Available in a full range of insulation colors for AWG sizes 18–4/0.
Application
- Switchboards & Panelboards — Internal wiring of circuit breakers, contactors, and relays in power distribution enclosures.
- Industrial Control Panels & MCCs — Control circuit and power distribution wiring inside motor control centers and automation cabinets.
- Instrumentation & Automation Systems — Connecting PLCs, sensors, and instrumentation devices within protected enclosures.
- Power Plants & Substations — Low-voltage control wiring for switchgear and distribution boards.
- Commercial Electrical Panels — Terminal connections and appliance internal wiring where 90°C rating is specified.
