Use one.
Composite rod insulator for high voltage transmission line, fixed and insulating high voltage wires. This product is especially suitable for polluted area, can effectively prevent the pollution flashover accident of transmission line, is a new generation product of the widely used of porcelain and glass insulators.
Two. Structure and properties
Composite insulator is composed of an umbrella cover, and both ends of the mandrel hardware composition, for the 110kV and the following products, unworthy of the equalizing ring, and above 220kV products with 1 ~ 2 equalizing ring (see Figure 1, figure 2, figure 3). According to user needs can also equipped with a pressure equalizing ring.
1 by silicone rubber is made of macromolecule polymer matrix to the umbrella has good hydrophobicity, corrosion resistance, aging resistance and other advantages. Can effectively prevent the pollution flashover accident occurred, and reduce the manual cleaning, free of measuring zero maintenance, provides a reliable guarantee for the safe operation of transmission lines.
2 the mandrel adopts glass fiber reinforced resin rods made, with tensile strength is very high (> 1100Mpa), about 1.5 ~ 2 times of the ordinary steel, high strength porcelain 3 ~ 5 times. In addition the mandrel has good damping property, creep resistance and anti fatigue fracture.
3 fittings and mandrel connected with no damage mechanical crimp type connection, which is the connection mode of the most advanced international. Its advantages are: coupling is safe and reliable, pressure stress distribution is uniform, and no damage to the integrity of the mandrel glass fiber bundles, can give full play to their excellent properties of high tensile strength.
4 pressure equalizing ring can improve the electric field distribution, reduce corona and radio interference, umbrella skirt is not burned out in the strong arc. The effect of high voltage composite insulators are more significant.
5 composite insulator has the advantages of compact structure, small volume, light weight (for the porcelain insulators of 1/7 ~ 1/10), with good flexibility, does not need to be cleaned regularly. Therefore, not only to bring great convenience transportation, installation, and greatly reduce the amount of maintenance and save a lot of maintenance costs, reduce labor intensity of workers, but also for the maintenance of accidents and implementation provides a good condition of compact transmission line.
6 composite insulator by integral injection molding production process. Umbrella outside appearance, interface less, mandrel and sheath bonded firmly seamless, inner insulation performance is good, can prevent the occurrence of interface breakdown phenomenon.
Three models and implications of product.
Four. Using the pre inspection
1 products factory prior to the standard one by one test and sample test, in order to prevent the transport process is damaged, the installation of the former should also gradually carefully check. Insulator umbrella surface defects (such as lack of glue, the indentation depth is less than or equal to 1mm) area is less than or equal to 0.2% of the total surface area of insulator.
2 if the umbrella of a tearing or wear and the core is exposed please don't use.
Five. The product packaging
The 1 insulator used the provisions of JB/T9673 packaging.
The 2 insulator is installed in the carton packaging firm, suitable size, convenient transportation.
Packing in cartons and below 3.220kV product, 10kV product of 6 per box supporting products, 35kV ~ 220kV products of each box 3 products. 330kV ~ 750kV products use round paper tube packaging, each tube are arranged 1 supporting products. 330kV ~ 750kV in the packaging, in order to protect the product from damage, a supporting plate fixed insulator first with 3 radial, which is then mounted in a circular tube, finally the paper tube is encapsulated with plastic bag.
4 each packing box with product certification, with the goods of 3 to 10 portions of the instruction for use.
5 pressure equalizing ring another carton packaging, 220kV and the following products equalizing ring the cartons with 3, 330kV and the above products are pressing ring carton built-in 2, equalizing ring comprises assembling bolt, nut and spring washer together.
6 in order to ensure the safe arrival of goods, packaging cartons are clearly marked on all right, so as to avoid the possibility of loss or mistakenly send result because the label is not perfect packaging and incomplete or illegible. Packaging body marked with various annotations, with packaging see product packaging description.
Six note the installation of the product.
The 1 insulator should be stored in dry warehouse, and should take the rat prevention measures, storage should avoid oil and petrochemical goods.
2 in the transportation process, should not be fittings and other heavy weights stacked directly on the insulator, so as to avoid damage to the insulator umbrella, so the packing box should be at the installation site to the out of the box.
We must pay attention to 3 out of the box, do not let the sharp cut umbrella skirt.
4 at the installation site, for longer insulator, do not be insulator dragged walk on the ground.
5 for 330kV and the above products, should pay attention not to insulator bend too, in order to avoid the mandrel excessive bending stress
Insulator 6 manual handling of very long, more than two or two shall carry, in order to avoid the middle part of the umbrella skirt surface caused by the sag was bruised, influence the electrical properties and the service life of the insulator.
7 in the hoisting insulator, do not allow the rope hanging in the shed directly, but should be hanging in the end attachments that ball on.
8 installing equalizing ring, certainly must pay attention: the ring equalizing ring is a smooth surface for insulator umbrella skirt.
9 don't trample or climbing composite insulator.
10 don't tread on the installed equalizing ring or a hanging rope cable and the weight in the equalizing ring, so as to avoid the equalizing ring loose or damage the surface.
11 during the installation process, to avoid excessive bending or torsion stress on the mandrel. At the same time in the hanging line, do not turn the insulator has a fixed or add load.
Ordering instructions seven.
When ordering please specify 1 product models, specifications, quantity, and delivery date.
2 in addition to providing our composite insulators with various standard structure, can be designed and made according to the special requirements of users.
