S9 series 35KV-level transformer
S9 series 35KV-level transformer

Detailed Product Description


35kV-class three-phase double-winding 9 OLTC transformers, the use of three-phase three-column core and columns, such as conjugate-section, using high-quality cold-rolled grain-oriented silicon steel sheet, 45 ° oblique joints, non-piercing, semi - dry glass banding tape. The use of high-quality oxygen-free copper wire coil, coil structure of advanced coil supported by the upper and lower parts folder. Body insulation increases Kok, using a thin paper tube structure of small oil gap. 8000kVA and above the oil reservoir equipped with anti-aging counters divide pointer with the end of the oil level in terms of ease of observation of the oil reservoir inside surface height, when the oil surface height above or below the oil surface, the oil level gauge Contact can be on-alarm device. Transformers and OLTC settings their oil, their respective connecting pipe equipped with gas relays, relays gas when the gas reaches a certain, contact closure alarm. Transformer 630kVA and above equipped with a pressure release valve at the top, when the tank pressure increased to 55kPa, the contact closure alarm and pressure release valve automatically opens when the tank pressure down to turn off automatically when 29.5kPa. Thermal performance of cooling devices using well-type radiator, radiator side air-cooled transformer with high winds in the volume of low-noise fans to ensure that the transformer in a full load in the safe operation of the load. This type of product to meet the performance parameters GB/T6451-2008, low loss, good stability, high reliability, it is applicable to 35kV-class transmission and distribution lines, high practical value, conservation of energy.
