2LOCKCS 0.230mm Self Bonding Enameled Copper Wire Class155 Black PU Winding Wire
2LOCKCS 0.230BK 0.230mm Enameled Copper Wire is cost-effective Class155 black self-bonding polyurethane winding wire, made per standard 2LOCKCS industry specification. Adopting double-layer coating design: inner polyurethane insulating layer + outer thermal self-adhesive bonding layer, with matte uniform black outer surface. Different from ordinary common enameled wire, it realizes thermal self-bonding shaping without extra glue dispensing, simplifies coil winding process. Class155 stable heat resistance fits long-term light-load operation of consumer audio coils, with direct solderable performance, greatly lowering production cost for coil manufacturers.
- Standard 2LOCKCS Spec: International standard model 2LOCKCS, fixed precise 0.230mm wire diameter, uniform black self-bonding paint film, compatible with global automatic winding equipment.
- Class155 PU Insulation Grade: Standard 155℃ heat resistance, anti-aging for daily light-load continuous working, perfect for civilian audio and electronic coil scenarios.
- Premium Thermal Self-bonding Performance: Outer self-adhesive layer features high bonding strength, fixed coil shape after heating curing, no glue overflow, no coil loose, high finished product yield.
- Direct Stripping-free Soldering: Polyurethane insulation can be soldered directly without paint scraping, save manual processing time, improve factory winding efficiency.
- Smooth Black Low-friction Film: Compact uniform black enamel surface, anti-scratch, no peeling during high-speed automatic winding, adapt high-volume automated production.
- Stable Conductivity & Cost Saving: High-purity oxygen-free copper core, stable resistivity, no sound distortion for audio coils; economical grade for mass civilian order procurement.
- Full Industrial-grade Certifications: Passed UL, RoHS, ISO, IATF certification, meet global import customs standards for Europe, America and Southeast Asia.
