Splice for steel core: Steel/ hot dip galvanized. (blue mark, inside surfaces gritted)
Filler splice: Aluminium alloy (black mark, non-gritted)
Splice for aluminium: Aluminium alloy (green mark, inside surfaces gritted)
Line splices VAG are used as full tension splices for connecting ACSR or AACSR (see remark) conductors.
Line splices consist of 2 to 4 sets of spirals, coloured differently:
- splice for steel core
- if necessary 1 or 2 filler spirals to fill the gap between diameter of steel splice and outer diameter of conductor
- splice for aluminium layers
The sets with same marking belong together.
Attention! The lay direction of the line spices has to be equal the lay direction of the outside cable layer.
For repair purpose you also can use line splices in parts (e. g. use only the green marked splice for aluminium).
Rods made of aluminium alloy, the inside surface of the rod sets is gritted up to D1 = 22,5 mm.
Additional information
Line splices VA are used as full tension splices for AAC conductors. For ACSR and AACSR conductors they can be usred as non-tension splices.
The line splices with rod dia. ≤ 6,35 mm are delivered in premounted rod sets.
The contact surface of the rod sets is gritted. All line splices with a rod dia. ≥ 7,87 mm are delivered as single rods.
Friction paste has to be applied to the conductor surface before installation. All line splices have a centre marking.
Important! The lay direction of the line spices has to equal the lay direction of the outer conductor layer
