Product Q&A

Q:Do your products comply with IEC or ANSI standards?

All fittings are designed and tested to IEC 61284, GB/T 2314 and ANSI C119.4. Full type-test reports from CNAS accredited labs or third parties are available to meet global grid access standards.

Q:How to guarantee mechanical load safety under strong wind, ice and external impact?

All hardware passes tensile failure, vibration resistance and ice coating load tests. Breaking load exceeds design standard by over 1.5 times to avoid line breakage and fitting falling under extreme weather.

Q:What quality inspection procedures do you implement before goods delivery?

Three-level inspection covering raw material incoming test, semi-finished patrol inspection and finished product sampling. Electrical & mechanical data are archived, and batch inspection reports can be supplied with shipments.

Q:Can you supply a full set of overhead line fittings for the whole distribution line?

Complete product range includes tension clamps, parallel groove connectors, insulation fittings, suspension clamps and protective hardware. One-stop supply streamlines procurement and shortens project delivery cycle.

Q:Can you handle large-scale utility bids, and how do you ensure quality consistency?

Supported by a self-owned factory with 111 million RMB registered capital and integrated MES system, all components are fully traceable. Every batch gets full mechanical & electrical testing for consistent mass production quality.
