Shear-off-head bolts lugs with angular position, electroplated. Euroseries 3НБЕ-(Л) (КВТ)

type : 3НБЕ-(Л)

  • Designed for connection of any type of cable cores: copper and aluminium, round or sector, mono - wire cables and stranded wires
  • Each lug is multilateral and caters to a range of cable sizes
  • X-shaped angular  location of the bolts corresponds to the European standards and guarantees the mechanical strength of the connection
  • The eccentric hole is provided for the cable core in the body of each lug
  • Operating voltage: up to 10 kV
  • Recommended for mounting heat-shrinkable kits and for equipping repair crews and emergency services 
  • Body material: special aluminum alloy
  • Body and bolts plating : electroplating
  • Corrugated knurling on the inner surface of the cylindrical part of the lugs increases the surface area and mechanical strength of the contact connection
  • The mounting on core is made by tightening bolts with shear-off-heads. The bolt heads are breaking at a fixed point, providing optimal mechanical and electrical properties of the contact connection
  • The construction of the bolts has several groove — stall "necks", so that the breaking of the head occurs on the level or below the surface area of the lug
  • Spade part of the lugs "КВТ" is shifted from the central axis and located a step below the cylindrical body
  • Spade part of the lugs, sizes 500/630 and 800 is located centrally-symmetrically in relation to the axis part of the lug
  • On the spade part of the lug there is an embossed marking, which indicates the nominal cross-section cable range and the manufacturer's logo
  • The size range of bolt connectors correlate with the size range of heat shrinkable sleeves, that is why bolt connectors has become ideal optional solution for sets of heat shrinkable sleeves
