Raw Material Inspection
Verification of electrolytic copper purity, flame-retardant PP/PC granules, and certified PVC insulation compounds.
Founded in 2006 in Jiande, Hangzhou, Zhejiang, Jiande Lyqen Technology Co., Ltd. is a dedicated custom manufacturer and exporter specializing in European, French, Schuko, UK, PDU, and IP44 waterproof power strips, extension cords, and heavy-duty cable reels.
Operating a modernized 5,000–10,000 square meter facility staffed by over 85 skilled personnel across 6 automated production lines, we maintain complete vertical control over every production phase—from copper wire drawing and PVC compounding to high-pressure injection molding, terminal spot welding, assembly, and testing.
Vertical integration guarantees strict quality oversight, raw material traceability, and prompt delivery schedules for international procurement.
Verification of electrolytic copper purity, flame-retardant PP/PC granules, and certified PVC insulation compounds.
Automated molding of socket enclosures, reel drums, and internal safety shutter mechanisms with tight tolerances.
Continuous insulation coating of copper conductors yielding consistent outer diameter and dielectric insulation thickness.
Overmolding European Schuko, French Type E, and UK Type G grounded plugs with robust strain-relief collars.
Multi-core wire bunching and stranding ensuring flexibility, high tensile durability, and minimal internal friction.
Permanent terminal welding eliminating contact resistance, avoiding overheating under high amp loads up to 16A.
Assembly line mounting of neon switches, thermal cut-outs, child protection shutters, and internal copper busbars.
Rigorous verification including high-voltage insulation tests, continuity testing, and contact pull resistance checks.
Sealed blister packs, color display boxes, barcodes, and reinforced corrugated outer cartons optimized for shipping.
Organized inventory palletizing and direct container stuffing with rapid ocean freight transit to Ningbo and Shanghai ports.
Our workshop houses high-precision equipment designed to produce electrical assemblies compliant with demanding European standards.








Every batch of power strips and cable reels undergoes rigorous electrical, mechanical, and thermal endurance testing to satisfy CE, GS, and ETL safety regulations.

100% full-check on functional continuity, earthing resistance, high-voltage breakdown, and cosmetic perfection prior to packaging.

Dedicated electrical bench instruments assessing insulation resistance, ground bond integrity, and over-current protection response.

Accelerated thermal and environmental aging under controlled temperature cycles to verify long-term polymer durability.

Simulating 16A maximum rating with high duty cycles to measure terminal temperature rise (ΔT) and prevent thermal cut-out failure.

High-precision optical dimensional inspection measuring pin distances, contact thickness, and plug gauge tolerances to 0.01 mm.

Mechanical stress testing assessing cord anchorage pull force, cable flex fatigue, and strain relief retention under severe pull loads.
