2PNCT, CUR-2PNCT-3PNCT Festoon Cable Technical

Item CUR-2PNCT Festoon Cable CUR-3PNCT Festoon Cable
Reinforcement Layer No built-in canvas cloth reinforcement between core bundle and outer sheath Extra canvas reinforcing layer wrapped under outer sheath
Mechanical Strength Medium tensile & impact resistance Heavy-duty reinforced, higher anti-tear, anti-lateral pressure
Travel Distance Limit ≤60m festoon travel Unlimited long-span heavy-load festoon
Reciprocating Frequency Medium daily cycles High-speed frequent reciprocation
Anti-Split Performance General Excellent, prevent sheath cracking under heavy self-weight
  • Operating temperature: -40℃ ~ +80℃ continuous
  • Standard: JIS C 3327 Japanese rubber flexible cable standard
  • Rated Voltage: 600V AC, Test Voltage: 3000V/1 min
  • Severe outdoor environment: UV, oil splash, snow, heavy friction.
  • Resist abrasion, ozone, mineral oil, weather aging, slight flame retardant

The CUR-2PNCT-SB, CUR-3PNCT Rubber Cable Install

Note：
1. CUR-3PNCT is mandatory for festoon travel over 60m or daily reciprocating cycles over 500 times
2. Flat PNCT-F variant is available for compact multi-cable festoon bundles to save installation space
3. Do not overload cable sag; excessive self-weight will cause sheath split, only reinforced 3PNCT can bear heavy load

Reeling-cable

Step 1 Festoon Trolley & Track Preparation
1. Install horizontal festoon I-beam track, ensure track level without tilt to avoid cable side extrusion
2. Match trolley roller size: roller diameter ≥10× cable outer diameter, rubber-coated rollers to reduce sheath abrasion
3. Set trolley spacing: max 2.0–2.5m for CUR-2PNCT; max 1.5–2.0m for heavy CUR-3PNCT to control sag.

Step 4 Two End Termination Fixing
Fixed end (crane main control cabinet): Use Kellem tensile grip to bear cable self-weight, avoid tensile force transferred to terminal lugs
Moving end (trolley terminal box): Reserve 1–2m loose cable allowance for full travel stroke, prevent tension pulling terminals loose
Strip insulation carefully without damaging copper strands; use tin-coated compression lugs, seal joints with heat-shrink sleeves for water & dust protection

Step3 Anti-Torsion & Protection Setup
1. Install swivel anti-twist joints at both cable ends to eliminate torsion during reciprocating travel
2. Add rubber guard plates at all track turning points, beam sharp edges to block sheath scratch
3. For outdoor application, install rain cover above festoon track to reduce long-term UV & rain erosion

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
Operator monitoring an extrusion line control panel in the TEBAOFLEX workshop

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
3.5 kV voltage withstand test station in the TEBAOFLEX laboratory

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
