Xhq5 Series 10kv 5ka Outdoor High Voltage Overhead Insulated Line Overvoltage Protector

Use environment:
1. Ambient temperature: -40~50 degrees;
2. Altitude: 2000m and below (recommendation: use special plateau products above 2000m);
3. Power frequency: 58-62Hz, (60Hz system), 48 -52hz (50Hz system);
4. The air in the installation site should not contain chemical corrosive gases, steam, and explosive dust;
5. For long-term use under abnormal conditions, the protector needs to be specially ordered, and it should be specified in advance:
1) Temperature or the altitude exceeds the standard;
2) There are damp or corrosive gases and impurities in the use environment (water, salt field, chemical plant, etc.);
3) Strong ultraviolet radiation (plateau, strong sunshine and arid areas, etc.);
4) Extremely polluted areas (mine work surface, construction site working surface, etc.).
Product installation: install
in parallel with the insulator (PS-15); first unscrew the bolt on the upper end of the current limiting element, press the positioning nail on the pressure plate on the stainless steel drainage ring into the positioning hole on the upper end of the current limiting element, screw on the bolt and tighten it . Then fasten the restrictor element tightly on the coupling. When installing on a pole, unscrew the nut at the root of the insulator (PS-15), insert the round hole of the connector of the protector into the bolt at the root of the insulator, so that the drainage ring is evenly placed around the insulator (PS-15), so that the distance between them (If the gap between the stainless steel drain ring and the insulator is uneven, you can adjust the angle of the drain ring, the position of the connector, etc.), and finally tighten the nut at the root of the insulator and the bolt at the lower end of the current limiting element.
The overhead insulated wire must be placed in the groove on the top of the rod insulator (PS-15) (not in the side groove); the gap between the stainless steel drainage ring and the insulated wire (core) must be controlled within the range of 60-100mm Inside, the gap between the diversion ring and the insulator must be uniform and controlled within 25±5mm; for overhead insulated lines that do not strip the insulation layer, the arcs of the three-phase diversion ring should face the same direction and must be placed outside to avoid gaps between the diversion rings. If the interval is too small, it will affect the insulation coordination of overhead lines.
The grounding terminal adopts a special grounding wire, and the grounding resistance should be controlled below 30Ω, such as using galvanized steel bars, steel strands or flat steel with a cross-section of 50mm2; for hilly and other mountainous areas, the grounding resistance is large, and a special grounding grid needs to be constructed.
It is recommended to install one set on the top of each base pole in areas where lightning damage occurs frequently; in other areas, one set can be installed every two base poles.
