Product Overview
30 kVA dry type transformer is an epoxy resin insulated, oil free, fire resistant, and environmentally friendly small distribution transformer. This 30 kVA dry type transformer is a 3 phase transformer suitable for 6.6kV/10kV/0.4kV power distribution systems, primarily used for voltage conversion, power distribution, and stable power supply. The product is compact, has low losses, low noise, requires no maintenance, and has strong short circuit withstand capability. This 30 kVA dry type transformer can operate safely for extended periods indoors, in basements, small factories, buildings, and computer rooms, and is widely used in industrial, construction, municipal, and overseas small power grid scenarios.
Our 30 kVA dry type transformers have a wide range of applications: they can be used as step down transformers to meet various voltage conversion needs, in small transformer systems for lower capacity applications, or as three phase distribution transformers in industrial power systems. Thanks to their reliable performance and standardized design, we maintain a reasonable inventory level for immediate delivery. We manufacture in strict accordance with multiple international and regional standards: IEC, GB, JIS, ANSI, IEEE, and UL, while meeting energy efficiency ratings (Level 1/Level 2) and SCB series requirements. All products have passed rigorous testing and certification according to the relevant standards.
