1. The non-compacted circular conductor belongs to the regular stranded conductor. When stranded, the conductor is pressed by the pressing wheel or the pressing die. The single conductor of the stranded conductor has a natural gap, and the conductor is circular. The most common one, such as stranded conductors and steel-cored aluminum strands of frequently seen wires, are non-compacting conductors.we are provide AAAC dead end grip.
2. The compacted circular conductor is based on a non-compacted
circular conductor. When stranded, the conductor is pressed by a circular pinch or a circular pressing die to reduce the single wire between the stranded conductors. In the gap, the conductor is still circular, the cross-sectional area
of the conductor is constant, but the outer diameter of the conductor becomes smaller, which can reduce the amount of materials such as cable insulation and sheath and reduce the outer diameter of the finished cable. Squeezed round
conductors are commonly used for low voltage, medium voltage and high voltage power cables and overhead insulated cables.
3. When forming a conductor, when the conductor of the cable is stranded, the conductor is pressed by a fan-shaped
or tile-shaped pressing wheel to press the fan-shaped, tile-shaped and semi-circular conductors. The conductor has a certain shape, so it is called a shaped conductor.
Cable skein: high pressure 300, monofilament diameter 3.2 required square to 270 square, how big is the mold, what is the specific formula?
The monofilament radius is 1.6 mm 270 divided by (1.6*1.6*3.14)=34. OK means that 34 aluminum wires with a diameter of 3.2 mm are required. Besides, is it not easy to skein? Directly use 300 skein Just fine, the steel core is also there.
Place the second set of splicing strips at the center mark and wrap one to two pitches on each side of the center. Install the third set of splicing strips in the same way. Fully assembled steel core splicing strip. To ensure reliable electrical connections, all wires, both old and new, must be thoroughly ground and installed immediately. A good quality conductive paste should be used to delay oxidation. Select the center mark of the set of outermost strips with the largest number of constituents to be carefully wrapped around the center mark. Place the second set of splicing strips at the center mark, wrap one or two pitches on both sides of the center, install the third set of splicing strips in the same way, and then wrap the second set and the third set of continuation strips simultaneously until Completely wrapped around. A fully installed tension splice, the end of the outer splice can be placed in place by folding the wire or turning the spline with the thumb.
In summary, it can be seen that the use of the tension pre-twisted wire repair method can cover the repair of the steel core aluminum wire with a damage area of more than 7%, and can even be used as a connection fitting for the broken
connection. Moreover, the construction process is simplified, the material is convenient to carry, the installation does not require other auxiliary tools, the construction personnel can operate independently after one teaching, and the
appearance after installation is smooth and beautiful. By adopting the repairing method, troublesome processes such as loosening of wires, tight lines, and clamping are avoided, labor intensity is reduced, labor productivity is improved,
and wire repair time is shortened, power failure time is effectively reduced, and power supply reliability is improved.
