Product Introduction

Compared with ordinary oil-filled power transformers Sealed Power transformer conservator canceled by rocker corrugated tank body as a heat sink cooling element. Rocker may vary with transformer oil volume expansion and contraction and expansion and contraction so that the interior of the transformer to the atmosphere, to prevent degradation of the insulating oil and moisture and aging.
Quality cold-rolled silicon steel core, effectively improves the magnetic flux density inside the core conditions, reducing noise, reducing the loss.
High strength enameled wire coil (or paper covered wire) wound cylindrical structure, a uniform distribution of ampere-turns, reasonable insulating structure, with strong short-circuit capacity.
Fastener used in the fuel tank retaining nuts are used, and will not be able to protect the loose run when the long-distance transport. Tank surface by the phosphate treatment using three anti (moisture, mildew, salt spray) coating, is widely used in metallurgy, petrochemical, and other harsh environment applications.

Features

◆ This series transformer compared to S9 transformer, load loss reduced by an average of about 30%.
◆ capacity in the range of low voltage winding of a foil 315-2500kVA structure, high mechanical strength, balanced ampere-turn distribution, good short-circuit capacity of the product.
◆ added to the body of the positioning structure, so as not to be displaced during transport, and installation of all fasteners fastening nut fastener to ensure that the product does not loose in the long run, does not meet the requirements of hanging core .
◆ corrugated tank transformers, the conservator canceled, along with the tank lid is completely welded or bolted, extend the life of the transformer oil.
◆ selection of components, are sealed and the transformer tank, according to the standard pressure release valve is mounted, the signal thermometer, gas relay, to ensure safe operation of the transformer.
◆ series appearance, small volume, the installation area can be reduced, is ideal maintenance-free high-quality products.
