Standard PVC wires crack, harden, and fail when exposed to repeated heat cycles or tight bending in compact devices. In appliances, lighting fixtures, and sensor assemblies, rigid wiring causes premature breakage, intermittent connections, and costly field returns.This 0.3mm² single core silicone rubber insulated wire solves that problem. Tin-plated copper conductor wrapped in flexible silicone rubber jacket — rated continuous operation up to 200°C. The ultra-soft construction bends easily in confined spaces without work-hardening or insulation fatigue. Designed for internal lead wires where space is tight and heat is constant.Core Specifications

Why This Wire Performs Where Others Fail— Stays soft at 200°C. Silicone rubber does not become brittle after prolonged heat exposure. Unlike PVC or PE insulation, it maintains flexibility through thermal cycling — critical for motor leads and oven-adjacent wiring.— Tin plating prevents oxidation. The tin-plated surface resists corrosion in humid or chemically aggressive environments. Solder joints form cleanly without flux — essential for automated assembly lines in electronics manufacturing.— Ultra-soft bend radius for tight housings. At 0.3mm² with silicone jacket, this wire routes through small channels, connector boots, and PCB tie points that stiffer wire simply cannot reach without cracking.— Consistent pull strength and abrasion resistance. The silicone jacket withstands repeated flexing in robotic arms, vibrating sensors, and moving appliance parts — tested beyond 10,000 bend cycles at rated temperature.Typical ApplicationsInternal wiring of household appliances (ovens, irons, heaters), LED lighting fixtures, temperature sensors, thermocouple extension leads, battery packs, medical devices, industrial control panels, and new energy equipment.Sourcing & CustomizationWe manufacture this wire in-house with strict IEC 60228 conductor tolerances.
