Class 5 bare copper conductor with TI1 PVC insulation and TM1 PVC sheath.
Separate insulation and outer sheath layers for fixed equipment and building wiring.
The original parameter table gives stranding, layer thicknesses, nominal overall diameter and weight for 19 single core sizes.
Match conductor cross-section and its stated voltage band to the circuit; assess current, voltage drop, grouping and route temperature.
Keep bends at or above 3 times overall diameter through 50 mm², and 4 times overall diameter from 70 mm².
Select suitable terminals for Class 5 conductors and specify sheath/core colours, cut lengths and packing. The listed operating range is -15°C to +70°C.
Typical locations include equipment rooms, plant rooms, distribution cabinets and protected routes serving telecom and low voltage equipment.
The stated range is 450/750V for 1.0-35 mm² and 600/1000V from 50 mm². Select the cable size and voltage band together.
6381Y uses Class 5 bare copper, TI1 PVC insulation and a TM1 PVC outer sheath.
The table contains 19 single core sizes from 1.5 to 630 mm², with construction dimensions and nominal weights.
6381B offers a Class 5 copper single core construction with XLPE insulation and an LSZH sheath for installations specifying low smoke and halogen free materials.
