Product Detail

Descripton：

Single-phase pad-mounted transformers are the preferred choice among base-mounted transformers, offering a balance of environmental friendliness, economic efficiency, high efficiency, and safety. These transformers utilize FR3 high-flash-point insulating fluid, providing excellent fire protection performance. Compared with traditional mineral oil transformers, their expected service life is significantly extended. The rated power of these transformers ranges from 10 to 167 kVA, and they are available in various designs such as ANSI Type 1, ANSI Type 2, and Ranch Runner, making them suitable for different application scenarios.

Features：

  • The FR3 fluid is not only biodegradable and non-toxic, but also capable of delivering sustainable performance at an affordable cost. This fluid strictly complies with the ASTM D6871-03 standard and meets the requirements of the IEEE PC57.147 standard which is under application.
  • The product performance fully meets or even exceeds multiple industry standards, covering ANSI (excluding the Ranch Runner front panel), NEMA, and DOE energy efficiency standards.
  • The core and coils are meticulously designed to achieve high reliability and significantly reduce the on-site failure rate. It offers two material options: grain-oriented steel and amorphous steel.
  • The overcurrent protection is well-configured, with Bay-O-Net fuses as standard, and optional current-limiting fuses or weak link components can be selected according to needs.
  • Both high-voltage and low-voltage bushing terminals are tinned, which can accommodate aluminum or copper conductors to ensure stable and efficient electrical connections.

Technical Parameters：

Specifications：

  • Meet or exceeds ANSI, NEMA and DOE2016 standards
  • IEEE standards C57.12.00, C57.12.38, C57.12.28, C57.12.35, C57.12.90, C57. 91 and C57.154
  • NEMA standards, NEMA TR 1 (R2000)
  • Department of Energy Efficiency Standard, 10 CFR Part 431
  • Tank coating exceeds IEEE Std C57.12.28-2005 and C57.12.29-2005 standards (stainless steel units only)
  • Full compliance with IEEE Std C57.12.28-2005 standard enclosure integrity requirements
  • FR3 fluid
  • Cores and coils designed for high reliability and low field failure rates: Available in grain-oriented electrical or amorphous steel
  • The transformer shall be designed in accordance with this specification and shall have an Average Winding Rise (AWR) of one of the following:
  • 55 °C, 55/65 °C, 65 °C
  • The applicable AWR rating shall be specified on the inquiry

What is Corona Effect in transmission？
What is Corona Effect in transmission？
Definition: The corona effect refers to the phenomenon where the surrounding air around a conductor ionizes, resulting in a luminous glow accompanied by a hissing noise.Air serves as a dielectric medium between transmission lines. In other words, it acts as an insulator between current - carrying conductors. When the voltage induced between conductors is of an alternating nature, a charging current flows between the conductors. This charging current increases the voltage of the transmission line

Discussion on Faults of Rural Power Grid Distribution Transformers
Discussion on Faults of Rural Power Grid Distribution Transformers
1. IntroductionDue to long - term operation, faults and accidents of distribution transformers in rural power grids cannot be completely avoided. These faults and accidents are caused by a multitude of factors, such as external forces like damage and impact, and irresistible natural disasters such as lightning strikes. Meanwhile, in some rural areas, the low - voltage lines are inadequately maintained, frequently resulting in overloading and short - circuits, which cause distribution transformer

Transmission Lines
Transmission Lines
A transmission line serves the crucial function of conveying electrical power from generating substations to diverse distribution units. It effectively transmits voltage and current waves from one end to the other. Structurally, a transmission line consists of a conductor that maintains a consistent cross - section throughout its length. Meanwhile, air functions as the insulating or dielectric medium situated between the conductors, playing a vital role in preventing electrical leakage and ensur
