0.1mm, 0.15mm, 0.2mm & 0.3mm.
Dia of Strands for 1.5 Sq.mm can be:
a. Incase of 7 Strands - 7/0.52
b. Incase of 0.3 mm dia each - 21 Strands
c. Incase of 0.2 mm dia each - 48 Strands.
What is the Core / Pair Identification incase of LDPE Insulated Cable?
By Colour or By Number printed Al-Mylar Tape / Polyster Tape.
What is the Purpose of Screening?
To reduce the interference by nearby sources.
What are the different types of Screenings?
a. Al-Mylar / Cu-Mylar Tape
b. ATC or ABC Braiding.
Which type of Screening is Cheaper?
AL-Mylar.
Noise in Instrumentation Cable is called?
Reduction of Accuracy of Signal passing through the Cable.
What is Thermocouple Extention Cable?
Thermocouple Element material & Thermocouple Cable Conductor materials are same.
What is Thermocouple Compensating Cable?
If the Electrical properties of the Conductor material used for the Thermocouple Cable is almost similar to that of Thermocouple element material it is called Compensating Cable.
Why there is no Compensating Cables for Tx, Jx & Ex Type T/C Cables?
This Thermocouple Element material itself is cheaper.
What will be the Normal Insulation Thickness for Telephone Cables?
a. Core Insulation - 0.2, 0.3 mm
b. Sheath - 0.5 to 1.2 mm.

Instrumentation Cables are Pair constructed.
What are the normal sizes of Control Cables?
1.5 & 2.5 Sq.mm
What will be the normal Conductor sizes for instrumentation / RTD Cables?
0.5, 0.75, 1.0, 1.5 & 2.5 Sq.mm
Thermocouple Cable Conductor normal sizes for:
a. Single pair - 16 AWG (1.295 mm dia)
b. Multi pair - 20 AWG (0.813 mm dia)
What are the standards for T/C Cables?
IS-8784, ANSI MC 96.1 (Please refer our Catalogue for other Standards.)
What is the Temperature Tolerance (+/- deg. C) allowable for Thermocouple cables for T/C Cables?
a. IS 8784 +/- 3 Deg. C
b. ANSI MC 96.1 +/- 2.2 Deg. C
