IMPLOSIVE COMPRESSION FITTINGS
FOR ELECTRIC TRANSFER SYSTEMS
VP metall AS develops, tests, manufactures and sells implosive luminaires to line builders and wholesalers within line materials in the Nordic region. The luminaire includes: full tension joints, tensioners, loop sleeves, repair sleeves, repair joints, mountings and various other luminaires.
The implosive method basically replaces hydraulic pressing of friction joints. A metal tube is subjected to an external overpressure upon detonation. The pressure is many times greater than the flow limit for ordinary metals and leads to compression of metals and line. Tensile strength meets the Scandinavian requirements for mechanical strength, and is certified to hold 90% of the specified breaking load of the line. The luminaire is type approved according to international standards in terms of electrical conductivity. The luminaire can be used on dry lines, on fully greased alloy lines and feral lines with greased steel core. It is designed for all standard line types.
The system provides:
Uniformly high quality
Only radial deformation
Reduced installation time
Beneficial overall economy
The luminaire is marked with type and year of manufacture. The boxes are marked with type and approved for transport and storage of explosion fittings. Each box contains assembly instructions.
EXPLOSIVE COMPRESSION FITTINGS
FULL TENSION JOINTS
The joint consists of a main pipe in aluminum coated with explosives.
FULL TENSION REPAIR JOINTS
Full tension repair joints are used during the replacement of defective joints and substantially simplify this work.
The jumper terminals consist of an aluminum main pipe coated with explosives and with contact surface at one end.
A dead end consists of an aluminum implosive main tube and an all-purpose eyebolt as an end fastener.
Repair sleeves can be used on a whole line when one or more aluminum wires in the line are broken or damaged. The explosive is here attached to one half and taped together before detonation.
SERVICE AND TRAINING
Should service / assembly assistance be needed, VP Metal can assist. This also applies if there is a need for training.
