Specify the pair and core arrangement together for an RS485 RVVSP twisted shielded cable. Featured enquiries include two-, three- or four-core requirements and 18AWG. Match these requirements to the exact construction code and instrument, electronic or automation-equipment interface.
How are the pair codes and conductor sizes interpreted?
Catalogue codes include 2*2, 3*2, 4*2 and other arrangements with bare mm size references. The broader description lists two, four, six, eight, ten or twelve cores. Provide the required pair map, total conductor count and actual area or AWG size with its units. A selected 18AWG request needs its own agreed code and drawing.
- The described conductor material is copper.
- Stranded construction is stated.
- PVC identifies the insulation material.
- The described cable form is round.
- The screen combines aluminium foil and tinned copper.
What should the equipment drawing establish?
The stated electrical designation is 300/300 V. Assign conductor functions and terminal destinations, then define strand dimensions, finished layers, pair arrangement and screen connections. Give actual load, routing, exposure and full thermal requirements. For the intended RS485 interface, specify its required transmission and electrical parameters with the selected cable construction.
How should lengths and packing be requested?
OEM/ODM enquiries should link each finished equipment-connection length to its pair/core code and termination drawing. The catalogue offers 1 m; packing is stated as 100 m per roll and the minimum order as 100 metres. Agree the required supply arrangement and total quantity without treating roll packing as the selected finished lead length.
