What Standards and Certifications Should 130° Three-layer Insulated Wire Comply With
2026-11-05
When specifying 130° Three-layer Insulated Wire for transformers, inductors, or switching power supplies, engineers must confirm that the wire meets the applicable safety and performance standards before design freeze. Huaying manufactures 130° Three-layer Insulated Wire to recognized international requirements, and the following guide summarizes the key standards, certification marks, and verification points that matter during selection and audit.
Core Standards Framework
130° Three-layer Insulated Wire is typically evaluated against both insulation-system standards and component safety standards. The table below lists the most commonly requested references.
| Standard / Specification | Scope | Typical Relevance to 130° Three-layer Insulated Wire |
|---|---|---|
| IEC 60317 series | Technical requirements for winding wires | Conductor dimensions, insulation thickness, electrical and mechanical properties |
| IEC 61558 / IEC 62368-1 | Safety of transformers and electronic equipment | Reinforced insulation and creepage/clearance verification |
| UL 1446 | Insulation systems | Class B (130°C) insulation system recognition |
| UL 2353 | Small-diameter triple-insulated wire | Component recognition for triple-insulated constructions |
| IEC 60950-1 (legacy) / IEC 62368-1 | IT and AV equipment safety | Reinforced insulation acceptance in end products |
| RoHS / REACH | Restricted substances | Material compliance for global markets |
Key Certification Marks to Verify
-
UL recognition — confirms the wire is listed for use in recognized insulation systems.
-
cUL / CSA — supports North American market acceptance.
-
VDE / TÜV — common for European reinforced-insulation approval.
-
CQC — relevant for China market compliance.
-
RoHS / REACH declarations — required for material compliance documentation.
Huaying supplies 130° Three-layer Insulated Wire with documentation packages that support these certification routes, including insulation-system compatibility data and material declarations.
What Auditors Typically Check
-
Confirmation that the wire is qualified within a Class B (130°C) insulation system.
-
Dielectric strength test records for reinforced insulation.
-
Pin-hole and concentricity test reports.
-
Traceability of insulation materials and conductor lots.
-
Valid certificate scope covering the specific wire construction.
Frequently Asked Questions
Q: Does 130° Three-layer Insulated Wire provide reinforced insulation on its own?
A: Yes, when qualified within an approved insulation system, 130° Three-layer Insulated Wire can provide reinforced insulation, allowing designers to reduce creepage and clearance distances in transformers and power supplies, provided the end-product standard and insulation-system recognition are both satisfied.
Q: Which UL standard applies to 130° Three-layer Insulated Wire?
A: UL 2353 is the primary component standard for small-diameter triple-insulated wire, while UL 1446 governs the insulation system in which the wire is used. Both should be confirmed for a complete compliance picture.
Q: Can 130° Three-layer Insulated Wire be used in Class B insulation systems?
A: Yes. The 130°C temperature index aligns with Class B insulation systems, and Huaying provides insulation-system compatibility documentation to support design and certification review.
Q: What test reports should be requested for 130° Three-layer Insulated Wire?
A: Request dielectric strength, pin-hole, concentricity, elongation, and adhesion test reports, together with RoHS and REACH declarations and valid certificate scope covering the ordered construction.
Q: Is 130° Three-layer Insulated Wire RoHS and REACH compliant?
A: Huaying 130° Three-layer Insulated Wire is supplied with RoHS and REACH declarations, and compliance documentation is available for customer audits and end-product submissions.
