Chlorosulfonated Polyethylene Insulated Electronic Wire (UL 3591)

Executive Standards
This product strictly follows internationally leading technical specifications for appliance wiring material:
- UL 758-2022: Standard for Appliance Wiring Material (AWM).
- Complies with RoHS and REACH environmental directives.

Core Model and Voltage Rating
- Common model: UL 3591.
- Rated voltage: 1000 Its high voltage rating design enables wide application in internal power distribution and high-voltage signal control for high-power equipment.

Product Specification Range
The conductor uses high-quality annealed copper wire or tinned copper wire, with precise specification design covering both signal transmission and power connection needs:
- Specification range: 22 AWG – 4/0 AWG.
- Conductor construction: Stranded fine copper wires, offering good bending flexibility.

Core Technical Parameters
1. Rated temperature: Typically 90 °C or 105 °C (according to specific process requirements).
2. Insulation resistance: Excellent volume resistivity, maintaining high dielectric strength even in humid environments.
3. Flame retardant performance: Passes the UL VW-1 vertical flame test, offering good self-extinguishing properties and fire safety.
4. Environmental endurance: Strong resistance to ozone and ultraviolet ageing, and very high resistance to mineral oils, various acids and alkalis, and chemical solvents.

Cable Structural Characteristics
- Conductor layer: High-purity bare copper or tinned copper conductor (Class 5 or Class 6 flexible conductor) ensures sound electrical conductivity and oxidation resistance, and is easy to solder.
- Insulation layer: Extruded specialty chlorosulfonated polyethylene (CSPE) compound. This material not only provides stable electrical performance but also features strong mechanical and physical properties such as cut-through resistance and abrasion resistance. The insulation thickness is uniform and easy to strip for processing.
- Colour identification: The insulation layer has rich, durable colours, facilitating identification and wiring in complex circuit systems.

Applicable Scenarios
- Motors and transformers: As lead wires for high-temperature motors or internal connection wires for transformer windings.
- Specialty industrial equipment: Environments with oil contamination and chemical splashing, such as petrochemical control cabinets and iron and steel metallurgical automation lines.
- Outdoor electrical facilities: Due to its strong UV resistance, suitable for connecting external electrical equipment exposed to sunlight for long periods.
- New energy systems: Internal wiring of energy storage control cabinets and high-voltage power electronic equipment.

Selection and Storage Recommendations
- Anti-interference selection: When used in electromagnetic environments with very high signal purity requirements, it is recommended to combine with metal shielding conduits or select related derivative models with shielding construction.
- Compatibility check: During selection, reference the AWG wire gauge ampacity table according to the actual operating current of the equipment to ensure sufficient safety margin at the rated voltage of 1000 V.
- Storage environment: The cable should be stored in a ventilated, dry indoor area. Although chlorosulfonated polyethylene has good stability, long-term storage should avoid direct contact with highly volatile strong organic solvents.
- Installation reminder: As CSPE material is slightly harder than ordinary PVC, in extremely cold environments (below -15 °C), appropriate preheating is recommended before installation to prevent insulation cracking due to cold brittleness.
