Two, outdoor high voltage Through-wall casing manufacturers
1, Yueqing Xijiang Electric Co., Ltd. is mainly engaged in the research and development and production of high-voltage surge arrester, indoor and outdoor vacuum circuit breaker, vacuum interrupter, disconnecting switches, through-wall casing, and other products, and has the comprehensive ability to meet the needs of the customer under specific conditions and provide good after-sales service.
The company has domestic first-class assembly lines and testing equipment, and a group of professional technicians who have been engaged in the production of vacuum and switches for many years, and can carry out the characteristic test of high and low-voltage vacuum electrical products, the verification and calibration of the measuring equipment as well as the analysis of raw materials and other work.
The company has established a quality management system in strict accordance with IS9001;2000 standard, and the first batch of the company has been awarded the national CCC "mandatory certification," "CQC" export certification, production licenses and relevant type test certificates, which enables the company to produce high-quality products efficiently. In recent years, our company with excellent products and services to win the market, customers throughout the country in various provinces and cities, products are widely used in electric power, communications, gold, mining, petroleum, chemical, railroad and other industries.

Three, high-voltage through-wall casing installation method
(1) installation of through-wall casing aperture should be larger than the embedded portion of more than 5mm, the maximum thickness of the concrete mounting plate shall not exceed 50mm.
(2) rated current in the 1500A and above through-wall casing is fixed directly to a steel plate, the casing should not be around the formation of a closed magnetic circuit.
(3) When the through-wall casing is installed vertically, the flange shall be upward, and when it is installed horizontally, the flange shall be outward.
(4) 600A and above busbar through the wall casing end of the metal splint (except fasteners) should be non-magnetic materials, and its and the busbar metal connected to the contact should be solid, the thickness of the metal splint should not be less than 3mm, when the busbar is two pieces and above, the busbar itself should be fixed.
(5)When the oil-filled casing is installed horizontally, the oil storage cabinet and the oil sampling pipeline should be free of leakage, the oil level indication is clear, the position of the oil injection and sampling valve should be installed in the tour monitoring side, the oil injected into the casing must be qualified.
(6) casing grounding terminals and unused voltage extraction terminals should be reliably grounded.
If it is the intention to acquire high-voltage through-the-wall casing friends, then I recommend that you refer to the price of the product to start analyzing. And to be clear about their needs in advance, with reference to its classification standards for selection, such as rigid waterproof casing and flexible waterproof casing as a representative of the two types of high-pressure through the wall casing, their nature, function, applicable areas and corresponding to the crowd will be different, and just pay attention to the product parameters is not enough, we should also be combined with the use of environmental conditions to begin to analyze.
