PVC Extruded
Example Applications: Permanent Sensor Fabrication, Laboratories, Test Facilties, Short-run Extension Leads |
Symbols:
† = Available as a UL construction. Prefix construction code with a “U”
§ = Also available as a multi-pair construction
1 = Two singles twisted together without a jacket
2 = In multi-pair construction, outer shield only
3 = This construction code applies only to multi-pair cable |
|
PP: The least expensive jacketed extension wire insulation available. The PVC individual color-coded conductors are insulated with 15 mils (nominal) of PVC, then parallel conductors are given a 20 mil PVC jacket (35 mils for UL). The Jacket is easily stripped for separation of insulated conductors for assembly.

PAP: Single & Multipair cables with an overall shield are constructed by insulating the single conductors with PVC. One conductor of each pair is numbered and twisted with its counterpart. The twisted pairs are cabled with an insulated copper communications wire and the entire construction is wrapped with an aluminum/Mylar tape shield. A copper drain wire is applied under the extruded PVC jacket.

PAAP: This construction is the same as the PAP construction, with the addition of an aluminum/Mylar tape and drain wire over each single pair in the construction in addition to the overall shield. This provides isolation for each separate pair in the construction and eliminates internal and external noise in the circuit.
