ACSRの簡易な製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an expansion type steel core with an increased outer diameter by providing a gap between a steel core and an aluminum stranded wire layer provided on the outside of the steel core.
This paper relates to a simple manufacturing method for ACSR.

コストを高める等の欠点がある。 Conventionally, to increase the mechanical strength of overhead power transmission lines, ACSR is used, which has a steel wire (single wire or stranded wire) in the center and an aluminum stranded wire layer around the outer periphery. Furthermore, in order to improve the corona resistance of this ACSR, an expansion type ACSR is also used in which a gap is provided between the steel core and the aluminum stranded wire layer to increase the outer diameter of the ACSR. That is, as shown in Fig. 1, a steel core (7 strands) 1
It has a structure in which aluminum wire 3 is wound in two layers at intervals to provide a gap 4 around the outer periphery of the wire, and an aluminum stranded wire layer 2 is provided on the outside of the gap 4. Expanded type of structure like this
As shown in Figure 3, the ACSRA is installed on iron towers T 1 and T 2 via suspension clamps B and anchorage clamps C. However, since the expansion type ACSRA has a void 4 inside, it is not possible to attach a strong suspension clamp or retention clamp even if the suspension clamp or retention clamp of the conventional structure is used as is. In the case of a suspension clamp (the same applies to a straight joint), a collar is inserted from the end of the expansion type ACSR to fill the gap 4 and then the sleeve is compressed, but inserting the collar is cumbersome, and in the case of a suspension clamp, Because the collar can be inserted downwards, armor rods are wrapped around the outer periphery to reinforce it so that it does not collapse, and then the clamp is attached.However, installation is troublesome, and furthermore, a wide suspension clamp is used to prevent stress. However, it has a special design and lacks versatility.
There are drawbacks such as increased cost.

易に架設し得る膨張型ACSRとするものである。 In view of this, the present invention is an expansion type that does not have these drawbacks.
We have devised a simple manufacturing method for ACSR, which detects in advance the parts that correspond to the connection parts, retention parts, or suspension parts of the inflatable ACSR to be erected, and fills the voids in these parts with filler when manufacturing the inflatable ACSR. This is an inflatable ACSR that can be easily constructed by creating areas with no voids, and by firmly attaching suspension clamps, anchoring clamps, etc. to these areas, similar to conventional ACSRs.

のである。 Next, the present invention will be explained in more detail based on the drawings. Figure 1 shows an example of a cross-sectional view of the expansion type ACSRA of the present invention, which is the same type as a general expansion type ACSR, and has a structure in which a gap 4 is provided around a steel core 1, and an aluminum stranded wire layer 2 is further provided on the outside of the gap 4. It has a connecting part, a retaining part,
As shown in FIG. 2, the part corresponding to the suspension part is a solid type D in which the gap is filled with a filler material 5 of aluminum wire.

は、実施例では充填材５としてアーマーロツドを
用い、これを電線の撚線工程において、当該部分
に他の素線と一緒に撚合せてなる。 To install this full type D, the iron tower T 1 to be erected,
The positions of suspension parts, retention parts, etc. are determined in advance according to the span S of T 2 , the slackness of the expansion type ACSRA, etc.
When ACSR is manufactured, the gap at that position is filled with a filler to form a solid type D, so it can be easily installed. As a means for constructing this solid type D, in the embodiment, armor rod is used as the filler 5, and this is twisted together with other wires at the relevant part in the wire twisting process.
このような膨張型ACSRAは第３図に示すよう

けることができるのである。 Such an expansion type ACSRA is installed on iron towers T 1 and T 2 via suspension clamps B and detention clamps C, as shown in Figure 3, but the parts to which suspension clamps B and retention clamps C are attached are shown in Figure 2. Since it is a solid type D as shown, the suspension clamp B and the restraining clamp C can be firmly attached in exactly the same way as a normal ACSR.

使用し得る。 The position where this solid type D is installed is the expansion type ACSR.
It is determined by calculation based on the span, sag, etc. of the steel tower to be erected, or by precise measurement using an optical range finder, etc., but it may take a little longer as there may be slight differences due to the construction of the steel tower etc. Furthermore, since it is difficult to distinguish from the outer layer, it is convenient to mark the surface of the outer layer by applying color spray or pasting a marking piece during manufacturing. Furthermore, the filler 5 is not limited to armor rod, and various other materials such as collar can be used.

The parts that correspond to the connecting parts, retention parts, or suspension parts of the ACSR are detected, and the voids in these parts are filled with filler to form solid parts during manufacturing, so it is possible to easily create an inflatable ACSR with a solid part. , suspension clamps, retention clamps, straight sleeves, etc. are installed using the same accessories and construction methods as regular ACSR of this solid part, so they can be installed firmly and easily.
It has remarkable effects such as increasing the versatility of accessories and reducing costs without losing the characteristics of ACSR.
