Linear hardware for self-supporting insulated wires (SIW) for 0.4 kV overhead distribution lines

SB type special bolts

SB type special bolts are designed for securing the ES-type intermediate suspension set to wooden and reinforced concrete poles when the use of F 20 mounting tape is not feasible. On reinforced concrete poles, they are installed into technological holes. The products are manufactured according to TU 3449-005-52819896-2010.
