LT AB Cable: A Complete Guide to Specifications, Accessories, Price List, and Applications

LT AB cable, also known as low tension aerial bundled cable, is a type of electrical cable used for overhead power distribution. It is composed of several insulated conductors bundled together and covered with an overall sheath. The bundle of conductors is suspended from poles or towers using messengers and clamps. The main function of LT AB cable is to transfer electrical power from the substation to the end-user. The conductors are typically made of aluminum. The insulation is made of PVC or XLPE and is designed to withstand voltage, temperature, and environmental conditions. The sheathing protects the cable from external damage. In case of a fault, only the affected conductor needs to be replaced, instead of the entire cable.

LT AB Cable Specification

LT AB Cable of size 3X50+1X16+1X35 sq. mm is a multi-core cable that consists of 3 conductors of size 50 sq. mm, 1 conductor of size 16 sq. mm and 1 conductor of size 35 sq. mm. Here are some of the general specifications for this type of cable:

• LT AB Cable Size : 3X50+1X16+1X35 sq. mm.
• Voltage rating: The voltage rating for LT AB cables in India is typically 1.1 kV.
• Conductor material: The conductor material is usually aluminum or copper.
• Number of conductors: The number of conductors in this cable is 5.
• For Phase Conductors (50 sq. mm 3 Core Cable) = R, Y, B
• For Street Light Conductor (16 sq. mm) = SL
• For Neutral/Messenger Conductor (35 sq. mm) = N
• Insulation material: The insulation material is typically PVC or XLPE.
• Current carrying capacity: The current carrying capacity of 50 sq. mm LT AB cable is : 150 Amp.
• Fire resistance: The cable should have fire resistance properties as per the IS 7098 Part 2.
• Tensile strength: The cable should have a minimum tensile strength of 15 KN/cm2.

LT AB Cable Phase Identification

LT AB Cable Phase Identification refers to the process of identifying and labeling the different phases (or wires) in a low-tension (LT) cable. This is typically done to ensure proper installation and functioning of the electrical system. The standard method of identifying the phases in a 3-phase LT cable is to use the colors red, yellow, and blue for the three phases, respectively. 

To better understand the phase identification method of LT AB cable, see the figure below :
