Abstract

A composition for vulcanizing fluororubbers, which comprises a fluororubber vulcanizable with an organic peroxide, such as an iodine- containing fluororubber, a polyfunctional unsaturated compound and an organic peroxide which forms a decomposition product containing not more than 2 mol/mol, preferably 0 mol/mol, in total of acetone and t-butanol under vulcanization temperature conditions, such as dicumyl peroxide. No secondary vulcanization is necessitated for this composition because the moldings obtained merely by primary vulcanization have practically sufficient characteristics, particularly thermal resistance.

In the case of visceral care, as shown in Figure 5

This is because the light steel is made of steel, LP insulation and suspension insulators with excellent insulation have been used to maintain the insulation between phases of the distribution line and the insulation of wires and wires, wires and poles.

In addition to pressing the electric pole of the distribution line as a vertical load, three LP pins take three LP insulators as shown in FIG. 4, and 12 to 18 suspension insulators as shown in FIG. As shown in Figs. 2 and 3, the efficiency and efficiency of the LP insulator, the suspension insulator, and the polymer insulator are lowered, the working time is long, and the materials are required. Have a disadvantage

For example, based on the weight and material costs of LP insulators and suspension insulators delivered to KEPCO on July 20, 2001,

In the case of weight

The weight of one LP insulator is 8.035kg and it is 24.105kg when three 3-phases are installed.

In the case of suspension insulator, one weight is 3.030kg and it takes 12 pieces when constructing two phases of 3, so it is 36.360kg and 18 pieces when constructing three phases of 3, which is 54.540kg.

In the case of material costs

The LP insulator is 11,465 won each. It is 34,395 won when it is installed in three phases.

Suspension insulator price is 14,241 won per unit. It takes 12 units for two phases based on three phases, and 170,892 won.

In the case of labor costs, the price of labor and machinery equipment in the second half of 2001

The paying wage for each LP LP is 8,755 won.

It is 26,265 won since three three phases are installed.

Suspension incarnation per worker is 6,325 won

It is 75,900 won because it takes 12 constructions in two phases of three phases.

It costs 113,850 won because it takes 18 constructions in three phases of three phases.

Total construction cost is material cost + labor

For three-phase pin holders, the construction cost is: material cost (34,395) + labor cost (26,265) = 60,660

In case of built-in caution, double construction based on 3-phase

Construction cost is: material cost (170,892) + labor cost (75,900) = 246,792 won

Three constructions based on three phases

Construction cost is: material cost (256,338) + labor cost (113,850) = 370,188 won

There are four methods of constructing a conventional low voltage distribution line.

First, as a method of mounting the WO wire or OW wire to the pole, as shown in Fig. 11-pole band-rack band-low pressure insulator-a method consisting of wire

Second, as a method of attaching the WO wire or OW wire to the pole, as shown in Figure 16, a method consisting of pole-complete band-complete-M bolt-strap-insulator-wire,

Third, as a method of mounting the ACSR cable to the pole, rack band-rack-low pressure human insulator-human strap-dead and clamp-how to configure the wire

Fourth, there is a method of attaching ACSR-OC cable to Jeonju, as shown in Fig. 13, which consists of branch band-ball eye-suspension insulator-socket eye-dead and clamp-wire.

In addition, the construction cost is excessively increased due to the increase in material and labor costs due to the time required for the material assembly process and unnecessary materials such as racks, low pressure human insulators, human straps, socket eyes, and suspension insulators.

In order to solve the problems described above, the present invention manufactures an insulation block, an insulation rack, and an insulation ball eye using insulation materials such as FRP and polyethylene, so as to not only reduce the weight of the distribution line but also simplify the process of wire wiring and LP insulator and suspension. By reducing materials such as insulators, polymer insulators, racks, low-pressure insulators, human straps and socket-eyes, the assembly time is shortened and the cost of materials is reduced by reducing material costs.

FIG. 6 is made of the same specifications as M bolt hole, straight support hole, complete band hole, improved ball clamp hole, horizontal, vertical, length, etc. as shown in FIG. Insulation block is not hollow inside to reinforce strength

6, there are M bolt holes, straight support holes, complete band holes, and improved ball clamp holes. The M bolt holes are used to construct the inner column using M bolts in two insulation blocks as shown in FIG. 9 is used when attaching the straight support to the insulation complete, as shown in Figure 9, the hole is used to attach the insulation completed to the pole by using the completion band as shown in Figure 9 and Figure 10, Used to install the improved ball claws.

The left figure of Fig. 7 is a cross-sectional view of a straight support hole mounted on an insulation finish by using a spring washer, flat washer, nut, and lock nut. It has a structure that puts spring washer and flat washer in the upper part and flat washer and nut lock nut in the lower part and resists vibration as in general LP insulator mounting method.

It is attached to complete insulation

Fig. 10 shows that in the case of built-in caution, two insulation blocks are attached to the poles with a complete band 2 and 2, and the left and right sides of the insulation block are fixed with M bolts. In one view, the wires are joined without a suspension insulator or socket eye.

Alternatively, it can be constructed in one piece by using one band 2 room and one insulation band.

As described above, the existing finishing band and M bolt can be used as described above, and can be constructed in the same way as the existing light finishing, such as pin head, flat head column, creation column, interior column, single column interior column, etc. There is this

When installing low voltage OW wire or WO wire to the pole, if you use an insulation rack made of insulation material such as FRP or polyethylene as shown in Fig. 14, the rack band-insulation rack-OW wire (WO wire) Wires can be mounted to Jeonju without low voltage insulator

In addition, wires can be mounted on poles by installing an insulation rack on the insulation.

In case of installing ACSR cable or ACSR-OC cable on the pole, if you use the insulation ball eye made of insulation material such as FRP or polyethylene as shown in Fig. 15, branch wire band-insulation ball eye-dead end clamp-ACSR wire (ACSR) -OC wires) in order of the racks, low-pressure human insulators, human straps, suspension insulators, socket eye shown in Figures 12 and 13 can be mounted to the pole without the material

As described above, the insulated complete and insulated racks and the insulated ball eye have a charge converter and a complete charge, and a charge converter without LP insulator, suspension insulator, polymer insulator, or low pressure human insulator by securing insulation between the charging insulator and electric pole. This reduces the vertical load of the distribution line, and in the case of special high-end distribution lines, it has the effect of reducing ground faults in the event of an accident that the cable is separated from the LP to reach the finish or the jumper line reaches the finish. This will reduce material costs and labor costs.
