Composite tapes are divided into steel-plastic composite tapes, aluminum-plastic composite tapes, stainless steel-plastic composite tapes, aluminum (copper) foil tapes and Metalized film tapes, etc. The products are used in various communication cables, submarine optical cables, optical fiber composite overhead ground wires ( OPGW), power optical cables, program-controlled cables, signal cables, track cables, local telephone cables, radio frequency cables, special signal cables, various electronic cables, etc. The composite belt products have the following characteristics, three no: no knife marks, no lotus leaf edge, no joint in the middle; three flat: smooth, straight, flat end face; three: length 6km, width 1000km, narrow 12mm.

These characteristics make our products have an advantage, so that each user can realize their own interests in the process of choosing to use our products. Cables usually use copper-plastic composite tape, polyester tape, aluminum-plastic composite tape, filling rope, Flame-retardant cloth tape, high temperature ribbon, PPD embossed tape, CPP cable wrapping tape and other parallel cable mesh filling ropes have been used for many years, but the problem of "diameter" measurement has not been solved. Rules; the diameter measuring tools commonly used are straightedge, vernier caliper, etc.; the conventional measuring method is to read directly on the measuring tool, and the three cannot be effectively combined.
In the cross-section of the cross-linked cable, the plied cord is fan-shaped with curved sides, which is the result of being squeezed by surrounding objects. The size of this squeezing force and the "diameter" of the folded foam determine the area of the cross-sectional area of the curved-edge fan-shaped in use. The squeezing force is constant under normal conditions. If the use conditions are the same and the "diameter" of the stranded cord is appropriate, the shape and area of its cross-section can reach the ideal state, that is, to achieve the purpose of filling and rounding the cable. The "diameter" of the stranded cord cannot be measured directly.
Is it possible to design a How about a measuring instrument that simulates the use state of the stranded cable filling rope, and indirectly determines its "diameter" through some conversion? From this, the following method is produced: make a concave cross-section, which is mostly Kai-shaped, and place a pressure plate that is always vertical to the two vertical sides of the rectangular groove and can move up and down, and a certain force P is applied to the pressure plate. The parallel cord is placed in the groove, and the vertical side of the slot has scale marks, so that the diameter of the circle can be calculated according to the rectangular cross-sectional area of the parallel cord in this state.
