Q. What are the different sizes of the cables?
A. 0.75, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 10, 150, 185, 240, 300, 400, 600, (Dimensions are in Square mm).
Q. What is the use of cable gland?
A. Cable glands are used to protect against mechanical damages o cables during entering in junction box, MCC etc. it also give earth continuity of cable Armor and equipment body.
Q. What type of Cable gland used in Oil Field?
A. In explosion proof areas double compression glands are used to avoid the gasses entering in the electrical apparatus.
Q. What are the Cables used in Oil Field?
A. PVC – Poly Vinyl Chloride
XLPE – Cross Linked Poly Ethylene
LC – Lead Covered
SWA – Steel Wire Armoured
PILC – Paper Insulated Lead Covered
MICC – Mineral Insulated Copper Conductor
Q. What is MICC? Where it is used? What mineral used in this cable?
A. Mineral Insulated Copper Conductor and it is used for fire alarm systems and Lightings systems at Hazardous area without using conduits and Magnesium oxide is used as mineral.
Q. What types of Cable joint and termination kits used?
A. Cold Compound joint kits. Hot Compound joint kits and Heat Shrinkable joint kits,
Hot Compound Termination and Heat Shrinkable Termination kits,
Q. What is ferrule and where is used?
A. Ferrule is used to connect two conductors during jointing. Three types are Crimping Type and Soldering Type for High Voltage Cables as well as for Medium Voltage Cables and for Low voltages ferrules are PVC Insulated.
Q. Why Lead Covered Cables are used in Oil Fields?
A. Lead Covered Cables are used in Oil Fields due to avoid damages of PVC Insulation, by hydrocarbon gases and chemical corrosion.
Q. How many types of lugs are used?
A. Crimping type and Soldering type lugs are used for cable terminations.
Q. How to check the cable fault?
A. As follows:
· Isolate the cable
· Megger the cable
· Trace the cable fault through cable fault locator and cable route through cable route locator
· If the cable resistance is high use the burnout test kit
Before cutting the cable use spiking gun for safety
