High-voltage wall bushings have many other names in real life, such as high-pressure wall bushings, waterproof bushings, etc. According to different design properties, the products can be divided into rigid waterproof bushings And flexible waterproof casing, the former is generally used in basements and other locations where pipes need to pass through, while the latter is different. In addition, there are many high-voltage wall bushings available in price ranges and styles on the market, and the corresponding quality varies. As a consumer, the editor recommends that you analyze them based on the description below.

3. Installation method of high-voltage wall bushing

(1) The aperture of the wall bushing should be at least 5mm larger than the embedded part, and the maximum thickness of the concrete installation plate should not exceed 50mm.

(2) When wall bushings with rated currents of 1500A and above are directly fixed on steel plates, a closed magnetic circuit should not be formed around the bushings.

(3) Wall bushings. When installed vertically, the flange should be upward, and when installed horizontally, the flange should be outside.

(4) The metal splint (except fasteners) at the end of the busbar wall bushing for 600A and above should be made of non-woven fabrics. There is a metal connection between the magnetic material and the busbar, and the contact should be stable. The thickness of the metal plywood should not be less than 3mm. When the busbar is two pieces or more, the busbar itself should be fixed.

(5) When the oil casing is installed horizontally, the oil storage tank and oil sampling pipeline should have no leakage, and the oil level indication should be clear. The oil filling and sampling valves should be installed on the patrol monitoring side, and the oil injected into the casing must be qualified.

(6) The grounding terminal of the bushing and the unused voltage extraction terminal should be reliably grounded.

If you are interested in purchasing a high-voltage wall bushing, the editor recommends that you refer to the product. Start by analyzing the price. And you must know your needs in advance and make your selection by referring to its classification standards. For example, rigid waterproof casing and flexible waterproof casing are two representative types of high-voltage wall bushings. Their properties, functions, and applicability The fields and corresponding groups of people will be different, and it is not enough to just pay attention to product parameters. We should also analyze them in combination with environmental conditions.
