HT AB Cables are a very novel concept in overhead power distribution, as compared with conventional bare conductor in overhead distribution system, AB cable provides higher safety, reliability, lower power losses and ultimate economy by reducing installation, maintenance and operative cost. This superior system is ideal for rural distribution and especially attractive for installation in difficult terrains such as hilly areas, forest areas & coastal areas etc. These cables are designed, manufactured & tasted as per international specifications. AB cable is also considered for power distribution in congested urban areas with narrow lane and by- lanes. In developing urban complex HT AB cable is a better choice because of its flexibility for re-routing as demanded by changes in urban development plan.

HT AB cables are highly reliable and insulation has been developed to withstand extreme cold and intense sunlight. Disturbance and faults occur five to ten times more often in open wires lines than in AB cable lines. There is no risk in touching the live cable and the insulation reduces the number of short circuits and over voltage faults in overhead cables during thunderstorms. Few hardware accessories are needed which are different for different size of cables. Streets can be lit only at little extra cost by using the cable that have an extra conductor for lighting. The cable can be supplied with one or two insulated conductors for street lighting.

• In electricity theft prone areas.
• As placement of bare lines in rural are & narrow street with limited space.
• As placement of bare lines where reliabilities of power supply is of prime importance.
• In hilly terrains here cost of erection of overhead lines or underground cable becomes very high.
• As reinforcement of existing system with increase in voltage/current carrying capacity.
• For temporary supplies.
• HT AB CABLES - ADVANTAGES

  In comparison with bare overhead distribution line, HT AB cables have very high reliability in maintaining services because power and neutral conductors are insulated with the best dielectric, resulting in the following advantages:

  • Less fault rate on account of good protection against line and group faults by high winds, falling trees or birds specially in hilly areas and forests encountered in rural distribution networks.
  • High insulation resistance to earth in all seasons. Negligible leage currents and low losses.
  • Multiplexer circuits of power and telephone cables could be in the same set of poles.
  • Better adaptability to laid besides with existing overhead bare conductor system without any interference.
  • High capacitance and low inductance leading to low impedance of lines.
  • Lower Voltage drop, Higher current caring capacity  vis-a-vis better voltage regulation.
  • Longer Span and Longer distance lines are possible with better system stability.
  • AB Cable are more safer than bare cable.
  • It can be laid in dense vegetation and forest areas.
  • Additional Connection can be easily and quickly made with hot line connectors.
  • Overall lines cost reduced.
  • Maintenance is very Convenient.
  • Very difficult to tap AB Cables, thus reducing theft which leads to lower distribution losses.
  • Since the tension from the current caring conductor is totally removed by introduction of messanger wire the operating tempreature of conductor is 90’C as against 75’C therefore alowing  AB Cable to carry current equivalent to that of the same size.
