(N)3GHSSHCH Tunnelling Underground Mining Cable Installation Instructions
✔ Firstly, Before installation, inspect (N)3GHSSHCH Cable for damage and verify specifications match operating requirements.
- Avoid dragging, sharp friction and excessive bending;
- follow the specified minimum bend radius.
- Keep cables away from high-temperature sources and corrosive substances.
✔ Secondly, during laying, ensure proper tension to prevent overstretching the steel wire braid armor.
- For underground and mobile use, fix cables securely with dedicated fixtures.
- Terminate cores strictly per electrical standards, guaranteeing tight connections and good insulation.
✔ Lastly, after installation, conduct insulation and continuity tests.
Do not operate the cable until all inspections pass. Wear protective gear during work and comply with local electrical safety regulations at all times.

Quality Assurance
Testing at every stage in our own workshop and laboratory, from incoming copper to the packed drum.
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
- Suppliers and batch numbers are recorded so every drum can be traced back to its materials
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
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 (3.5 kV and higher) and partial-discharge measurement in the shielded HV laboratory
- Screen and pilot-core continuity checks for mining and reeling constructions
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
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
- Test report and packing list issued with every shipment
