Standards & Certifications
ISO 9001 quality management for cable production; ISO 14001 and ISO 45001 for sales and related management. UL and cUL (flexible cord), VDE (EN 50525-2-21), Korea KC, China MA and US MSHA approvals cover the certified types; CE is a third-party verification of conformity (VoC).
Manufacturing Process
From compound to shipment, the production steps and routine tests behind each cable length.
- 1
Compound preparation
EPR, CPE, PUR and silicone compounds are mixed and tested for hardness, tensile strength and elongation before use.
- 2
Conductor stranding
Tinned or bare copper is bunched and rope-stranded to Class 5/6 flexibility for trailing and reeling duty.
- 3
Insulation extrusion
Cores are extruded and continuously vulcanised; wall thickness and spark tests are recorded on every length.
- 4
Core assembly and screening
Cores, earth conductors, pilot and fibre-optic elements are laid up with the fillers and screens the type designation requires.
- 5
Inner and outer sheathing
Reinforced double-sheath constructions are extruded and cured for abrasion, oil and tear resistance.
- 6
Routine electrical tests
Conductor resistance, voltage withstand and insulation resistance tests at the levels set by the referenced standard.
- 7
Mechanical and ageing tests
Bending, tensile, hot-set, ozone and flame tests according to the referenced standard.
- 8
Marking, packing and shipment
Metre marking, drum packing and documentation for worldwide project delivery.
Cable Manufacturing Quality Control
Five-stage quality assurance from incoming copper to the packed drum.
- 01
Raw Material Inspection
Every batch of copper rod, rubber compound and reinforcing material is checked before it reaches the line.
- Copper: conductor resistance, elongation and surface condition on incoming rod and drawn wire
- EPR, CPE, PUR and silicone compounds: hardness, tensile strength, elongation and ageing samples from each mix
- 02
Manufacturing Process Control
Stranding, insulation extrusion, core assembly and sheathing run under recorded process parameters.
- Class 5/6 stranding with lay length and tension monitored for trailing and reeling flexibility
- Continuous-vulcanisation extrusion with wall thickness and spark tests logged on every length
- Operators sign off each stage before the cable moves to the next machine
- 03
Electrical Testing
Finished lengths go through the routine tests required by the referenced VDE, ICEA, IEC or NEK standard.
- Conductor resistance and insulation resistance on every length
- Voltage withstand test at the level set by the referenced standard
- Screen and pilot-core continuity checks for mining and reeling constructions
- 04
Mechanical and Ageing Tests
Samples from production are tested for the duty a mining, crane or submersible cable will actually see.
- Tensile strength and elongation of insulation and sheath before and after ageing
- Hot-set, ozone, oil-immersion and low-temperature bending tests
- Constant-temperature water bath for insulation resistance of submersible constructions
- 05
Flame Test and Final Inspection
Before packing, the cable is checked against the order and the flame-performance requirement of its standard.
- Single-cable vertical flame test to IEC 60332-1-2 where specified
- Metre marking, printing, drum length and appearance inspection
- Packing list with every shipment; test documents for the order confirmed at quotation
