DRUM FOR FIXATION OF COUPLINGS WITH LOOP CIRCUIT OF OPTICAL CABLE Russian patent published in 2010 - IPC H02G11/02 

FIELD: instrument making.

SUBSTANCE: invention relates to power engineering and may be used as drums for fixation of couplings with process loop circuit of optical cable. Drum represents a rigid frame assembled from elements (9, 10, 11) (round rods, section bars or strips) with bracket and connection points (2) for fixation of couplings (1). Bracket is arranged in the form of plate (3) with flanges (8) and vertical axis (4) welded into its centre, drum is put onto vertical axis (4) and is therefore fixed on bracket. Fixation of drum on round concrete support of overhead power transmission line is done by means of belt yokes fixed in shoulders of plate (3), and drum fixation on polyhedral concrete support (25) is done by means of angles in flat plate of bracket, where pins passing through support shaft are fixed.

EFFECT: drum for fixation of couplings with process loop circuit of optical cable differs by simplicity of design and installation, reliably protects coupling in process of operation, is characterised by low costs in production process and is manufactured serially and supplied on lines.
