The bolt lugs are designed for jointing conductive cores with a cross-sectional area of 25-240 mm. sq. rated for up to 35 kV. The lug is installed on the core by screwing the bolts with a hex key, the bold head snaps off when the specified torque is applied. The connectors provide reliable jointing and conductivity as per GOST 17441-84.
The connectors are made of grade B95 and D16T1 duralumin alloys.
One such connector can be used several cores of different standard sizes.
