LV ABC Assembly Transmission Line Fittings Accessories

  LV ABC ASSEMBLY

Overhead distribution line system can be categorized as either low voltage or medium voltage. Low voltage lines have an operating voltage up to 1kV. They may be either bare or covered. Covered lines may either be unscreened or fully insulated ABC Accessories System. In LV Aerial Application, fully insulated ABC are increasingly as being used almost only alternative to bare overhead or underground system in different parts of the world.

 LV ABC SYSTEMS

• Structure. Nomally three phases and one neutral messenger. 
• Self-supporting and suspended between supports (generally existing poles)
• ABC Bundle and accessories being fully insulated protect lineman actively as the design is touch proof.
• They are twisted together to form a bundle as there is no requirement of phase to phase clearance. Individual cores are separated only at dead ends, supports, joints and tap-offs.
• Prescribed clearance required for Bare Conductors under NEC/NESC/VDE/EDF codes not applicable here and the same may be reduced without limitation as long as insulation does not become vulnerable to mechanical damage.
• Prescribed clearance required for Bare Conductors under NEC/NESC/VDE/EDF codes not applicable here and the same may be reduced without limitation as long as insulation does not become vulnerable to mechanical damage.
• The conductors and joints are fully water proof. 
• Lower voltage drop and higher current carrying capacity.
