Specification

20 AWG 4P Solid Bare Copper Shielded Al Tape Tinned Drain PVC J-Y(St)Y Lg 300V Security Cable

Allowable Ampacity for 20 AWG 4P Solid Bare Copper Shielded Al Tape Tinned Drain PVC J-Y(St)Y Lg 300V Security Cable: 100 Amps

About:

This cable configuration specifies a single-pair (4P) cable with a 20 American Wire Gauge (AWG) solid bare copper conductor, shielded with aluminum (Al) tape, and incorporating a tinned copper drain wire. It is encased in polyvinyl chloride (PVC) and designed to meet the J-Y(St)Y Lg standard, suitable for 300V applications. This design is particularly engineered for environments where electromagnetic interference (EMI) could be a concern, providing reliable signal integrity and performance.
