Twisted 2 pairs shield instrument cable with SWA
Applications
These cables are widely used between variable-frequency power source and variable frequency motor, especially for paper making, steelworks, textile industry,metal processing,fan and air-condition.
Cable configuration
Conductor | Plain annealed copper (class 2 strands) of the type specified in AS/NZS 1125. |
Insulation | Numbered and colour coded high grade polyvinyl chloride (PVC 90 o C) compounds insulation to UL Style 1569. |
Laying-up core | Twisted to pair or triple with optimum pitch to minimise the cross talk |
Individually screened | A stranded tinned annealed copper drain wire (7/0.2mm) is helically applied between the lapping polyester tape and the aluminium foil (100% coverage) for protection against static noise, common mode noise and crosstalk between each pair |
Overall screened | A stranded tinned annealed copper drain wire (7/0.2mm) is helically applied between the lapping polyester tape and the aluminium foil (100% coverage) for extra protection against external noise and interference (i.e. electrostatic from external high voltages, electromagnetic from external high currents) |
Armour | Single layer galvanized (mild) steel wires for corrosion resistance |
Bedding and sheath | High grade (PVC 90 o C) Flame retardant to UL Style 2464. |
