Product Description

Product Description

Description:

This three-phase dry-type transformer is specifically customized for the harsh operating conditions of vacuum furnaces, integrating cutting-edge electrical technologies and extensive practical experience. It is a core component that ensures the efficient and safe operation of vacuum furnaces.
 

 

1.High Impedance for Safety

The high-impedance design is a critical safety feature of this transformer, precisely tailored to meet the stringent safety standards of the vacuum furnace's complex electrical environment. In the event of a short circuit, the surge in current is effectively suppressed by the high impedance, preventing hazardous arcs and overheating phenomena. This safeguards against equipment damage and safety accidents, creating a robust safety barrier for both operators and surrounding facilities, ensuring that the entire production environment remains safe and controllable at all times.

 

2.High Current for Heating

The exceptional high-current output capability is the key to achieving rapid temperature rise in vacuum furnaces. By precisely matching the electrical characteristics of the furnace's heating elements, the transformer delivers a powerful current that quickly activates the heating elements, enabling them to release high levels of heat and meet the high-temperature process requirements. Compared to standard configurations, it significantly reduces the preparation time for heating, helping the vacuum furnace reach an efficient operational state more quickly, accelerating the production process and substantially increasing capacity.

 

3.Premium Craftsmanship

The cylindrical core design features a compact form and exceptional magnetic permeability, laying the foundation for efficient energy conversion. Paired with the comprehensive vacuum pressure impregnation (VPI) process, the varnish penetrates into every gap, filling the winding spaces and enhancing insulation performance. Additionally, meticulous end-sealing treatment prevents the intrusion of moisture and dust, reinforcing the protective barriers from the inside out. This greatly extends the service life and ensures long-term, stable performance in production.
 

Operation Environment

A)  Altitude: Not exceeding 1000m, shall be derating used if above 1000m;
B)  Ambient Temperature: -25ºC~55ºC.
C)  Relative Humidity: ≤95%;
D) As to the installation site, to make sure no bad effect on transformer insulation, chemical deposition, dust, and other explosive or erosive medium.
E) The supply voltage approximates sinusoidal wave, and the three-phase voltage is relatively balanced.
