Bolted connectors with shear bolts, manufactured by Termofit LLC, are suitable for cables with both aluminum and copper conductors.
Bolts :
- Can be made of brass or aluminum alloy.
- They have 1 groove, the moment of breaking the bolt head is calculated based on the cable cross-section to ensure optimal electrical and mechanical connection. If necessary, bolts with 2 grooves can be made (so that when tightening cores of the maximum cross-section, there is no need to saw off and grind the remains of the bolt “body”).
- At the contact spot in the bolted connectors, a conductive lubricant developed by specialists from Termofit LLC is applied.
- The arrangement of bolts can be in-line (standard design), V-shaped (mainly for stranded conductors), in-line, double-sided (from 600 mm2) or in a circle (“hedgehog”, for cables from 110 kV)
Sleeve:
- The connector body (sleeve) is made of aluminum alloy. If necessary, you can make a Tin-Bismuth (Sn-Bi) coating (electroplating), chemical oxidation or nickel plating - an electrochemical method of protection from adverse external influences, a thin film protects parts from chemicals and moisture and extends the service life of the product .
- There is a grooved knurling on the inner surface of the connector body, which increases the area and mechanical strength of the contact connection.
- Cable connectors have a hole that matches the geometry of the cable conductor.
- For cable joints with oil-impregnated paper insulation, locking connectors are used. In this case, the sleeve body has a partition, which prevents oil from flowing from one cable to another.
By special order, Termofit LLC produces:
Transition connectors: used to connect cables with different cross-sections.
Branch connectors: used when it is necessary to connect a branch cable to the main cable.
Repair connectors: differ from ordinary ones in their elongated size.
Documentation:
