Standards & Certifications
JINXING states standards precisely — “designed to” and “certified” are different things. Each claim is labeled honestly and audited by technical staff before publish.
Quality Management Certification
ISO 9001:2015
Quality Management System — system certified. Covers design, manufacturing, and after-sales service.
ISO 14001
Environmental Management System — system certified. Environmental impact control during production.
OHSAS 18001 / ISO 45001
Occupational Health & Safety Management — system certified. Worker safety and workplace standards.
Product Standards (Designed To)
IEC 60076
Power transformers — international standard for design, testing, and rating. All oil-immersed and dry-type units.
IEEE C57.12.00
Distribution transformers — IEEE standard for North American and IEEE-compliant markets.
GB/T 6451
Chinese national standard for oil-immersed power transformers — for domestic projects.
CE Marking
EU compliance — per model, not blanket. Available for models destined for European markets.
Type Test Reports
Third-party witnessed type test reports on file — available on request for qualified inquiries.
Custom Standards
Design to customer-specified standards or local utility requirements (e.g., KPLC, EAC, GCC).
Material & Component Standards
Insulating Oil
IEC 60296 mineral oil, with breakdown voltage >70kV/2.5mm and moisture <10ppm.
Core Steel
Grain-oriented silicon steel (M3-M5 grade), low-loss, step-lap cutting.
Conductors
Paper-covered copper or CTC (continuously transposed cable) for large units.
Standards matched to each order
Applicable IEC, IEEE, national and utility requirements are confirmed during technical review. Certification and test evidence remain model- and order-specific.
