KEY FEATURES

• Class 5 bare copper construction for routing and termination in fixed equipment wiring.

• PVC insulation and a separate PVC outer sheath, with matching core and sheath colour choices.

• Size-dependent working voltage and an operating temperature range of -15°C to +70°C.

SELECTION NOTES

• Choose the conductor cross-section for circuit load, route length, voltage drop and the connection hardware used in the cabinet.

• Plan minimum bending radii of 3 times overall diameter up to 50 mm² and 4 times overall diameter from 70 mm².

• Specify the required colour identification, lengths and packing. Use green/yellow identification for its intended protective-conductor function in the circuit design.

FAQ

Which equipment uses 6381Y cable?

Telecom power supplies, switchgear, control panels and distribution cabinets use this cable for protected fixed single core connections.

What are the insulation and sheath materials?

TI1 PVC insulation surrounds the Class 5 copper conductor, with a separate TM1 PVC outer sheath.

How does conductor size affect working voltage?

The stated 1.0-35 mm² band is 450/750V, while sizes from 50 mm² are 600/1000V.

Which colour combinations are listed?

The listed matching sheath/core colours are blue, grey, green/yellow and brown; special colours can be ordered for the specified circuit identification.

How should cabinet routing be planned?

Allow the specified bending radius, suitable cable support and terminals compatible with Class 5 copper. Coordinate cable diameter with the entry and termination space.
