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.
Comparison to Other Constructions: Abrasion Resistance - Good Chemical Resistance - Fair Moisture Resistance - Good Relative Cost - Low
PTW:The least expensive extension wire insulation available. The PVC individual color-coded conductors are insulated with 15 mils (nominal) of PVC, then twisted together.

PTWP: The least expensive jacketed extension wire insulation available. The PVC individual color-coded conductors are insulated with 15 mils (nominal) of PVC, twisted together, then conductor pair(s) are given a 20 mil PVC jacket (35 mils for UL).

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

Foundries, Extensive applications in aluminum processing,
Preheating & Stress Relieving of Forgings, Heat Treating for
annealing, aging, or hardening, Homogenizing furnaces for
billet preheating, Furnace Temperature Surveys
Symbols:
‡ = All fiberglass is impregnated with a
high-temperaure resin to increase durability and
reduce fraying.
GG: Most popular and widely applied of all glass insulations. A color-coded fiberglass braid saturated with a high-performance resin is used for insulation of the single conductors and jacket.

Synthetic Braided
Example Applications:
Replacement for beaded
thermocouples, heat treating, coke ovens, soaking
pits, furnace survey thermocouples, brick & tile kilns,
closed tubes or protective atmospheres, glass and
ceramic manufacturing, metalworking plants

CFCF: Highest temperature flexible insulation available. The braided yarn is a composition of the oxides of alumina, boric and silicone. Each conductor as well as the overall jacket are braided with this high temperature yarn to provide maximum flexibility at extremely high temperatures.
Comparison to Other Constructions: Abrasion Resistance - Poor Chemical Resistance - Fair Moisture Resistance - Poor Relative Cost - High
MCFCF:This construction has a mica barrier tape applied to each single conductor prior to being insulated with the ceramic fiber yarns. The construction is identical to the CFCF construction except for the addition of a light jacket saturant and the mica tape, which protects against potential shorting from the black carbon residue which forms when the product is used in applications where the air supply is limited, such as thermocouples in protection tubes. The mica may also provide moisture protection during temperature cycling.
Comparison to Other Constructions: Abrasion Resistance - Good Chemical Resistance - Fair Moisture Resistance - Good Relative Cost - Low
RR: High temperature silica fibers are braided on the single conductors as well as the overall jacket. Because saturant is not used, this product is not recommended for abrasive applications. Each conductor as well as the overall jacket are braided with this high temperature yarn to provide maximum flexibility at extremely high temperatures. A tracer is braided into insulation for polarity and calibration identification.
Comparison to Other Constructions: Abrasion Resistance - Poor Chemical Resistance - Fair Moisture Resistance - Fair Relative Cost - High
SFSF: Tough, heavy insulation for use where abrasion resistance on braided insulation is required. Conductors are insulated with a braided composite synthetic yarn* & impregnated with a color-coded moisture resistant saturant. The insulated conductors are laid parallel & insulated with a heavy yarn composite synthetic fiber jacket which is then coated with the same saturant.
