Problems solved by technology

[0002] The original strain clamps in our country are mainly made of malleable cast iron, which has a large specific gravity and heavy clamps. When constructing overhead cables, it is necessary to wrap the outer layer of the conductors with aluminum foil and fasten them with U-shaped bolts. As a result, a closed magnetic circuit is formed, hysteresis and eddy current are formed, resulting in energy loss and huge waste

Abstract

The clamp comprises of body and inner fixture block. An inner clamping arresting pin is set up at the body corresponding to position of slideway in inner fixture block. The body and inner fixture block are made from high strength aluminium alloy. The invention lowers dissipation of energy, improving circuit equipment towards target of 'long service life, zero defects and exemption from inspection'.

Description

Technical field: [0001] The invention relates to electric equipment, in particular to a wire clamp suitable for distribution lines. Background technique: [0002] The original strain clamps in our country are mainly made of malleable cast iron, which has a large specific gravity and heavy clamps. When constructing overhead cables, it is necessary to wrap the outer layer of the conductors with aluminum foil and fasten them with U-shaped bolts. As a result, a closed magnetic circuit is formed, hysteresis and eddy current are formed, resulting in energy loss and huge waste. Invention content: [0003] The technical problem to be solved by the present invention is to provide a strain clamp made of high-strength aluminum alloy which can effectively overcome the above-mentioned defects and has remarkable energy-saving effect. The technical solution adopted by the present invention to solve the technical problem is that a strain clamp made of high-strength aluminum alloy is main...
