Product overview

PUR-JZ Control Cable is a flexible polyurethane-sheathed control cable for machine tools, automation, handling equipment and mobile industrial systems. The JZ designation commonly indicates numbered cores with a green-yellow protective conductor. PUR jackets are selected where abrasion, oil, weather and mechanical wear demand more protection than a standard PVC control cable. Confirm the exact core layout, voltage and motion duty before ordering.

Application & Features

Selection overview

Control cabinets, machine tools, robotics, conveyor systems, handling equipment, indoor/outdoor industrial machinery and occasional moving installations. Verify continuous-flex, torsion, drag-chain or reeling suitability separately.

Parameter Reference
Voltage Common control-cable classes are low voltage; confirm the exact rating
Temperature PUR compound and installation method determine the range
Bending Moving radius depends on core count, OD and motion cycles
EMC Unscreened JZ form; use a screened variant where interference control is required

Standards & References

Applicable standards

Confirm the exact VDE/EN construction standard, flame test, oil resistance and motion qualification for the ordered PUR-JZ cable.

Construction

Material and build-up

  • Conductors: Fine-stranded copper conductors for flexible service
  • Insulation: PVC or thermoplastic core insulation, with numbered cores
  • Protective conductor: JZ constructions commonly include green-yellow earth conductor
  • Outer sheath: Polyurethane (PUR), selected for abrasion and oil resistance

Quality Assurance

Testing at every stage in our own workshop and laboratory, from incoming copper to the packed drum.

Bare copper wire bobbins inspected before stranding at the TEBAOFLEX factory

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
Tensile testing machine for conductor and sheath samples

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
Single-cable vertical flame test chamber

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
