Exquisite Product Introduction
Shandong Zhifeng Transformer Co., Ltd. proudly presents the revolutionary S11 and S13 series, a new frontier in fully sealed oil-immersed transformers. Expertly crafted for AC power systems functioning at 50Hz and voltages up to 20kV, these transformers epitomize the pinnacle of technological advancement. They are ideally suited for a wide range of industries, including petroleum, metallurgy, chemical, textile, and light industry. Engineered to thrive in high-dust conditions, our transformers guarantee dependable and efficient energy distribution across numerous industrial applications, setting a new standard in performance and reliability.
Unique Product Features
Cutting-Edge Iron Core Design
At the heart of our transformers is a masterfully designed core, crafted from high-permeability, grain-oriented cold-rolled silicon steel sheets. This innovative structure features a fully oblique joint stacking iron core with a circular, multi-stepped cross-section for the core column. By equalizing the sections between the iron yoke and core, this pioneering design significantly enhances overall efficiency and performance, ensuring optimal energy usage.
Precision Winding Engineering
Our transformers feature expertly designed windings, incorporating a corrugated oil channel and replacing traditional paint dipping with precise tape binding. The meticulously crafted concentric coils include a high voltage winding complete with a crucial tap leading to the tap-changer. Conveniently mounted on the box cover, this allows for effortless adjustments to the power supply prior to tapping voltage changes, enhancing functionality and user convenience.
Enhanced Safety Protection Device
Available in capacities ranging from 30~2000kVA, our transformers are equipped with a pressure relief valve, ensuring superior safety and steadfast reliability.
For added peace of mind, optional gas relays with alarm and tripping terminals can be installed according to user preferences, adding an extra layer of protective security.
Precision Oil Temperature Measuring Device
Our transformers incorporate a carefully engineered glass thermometer tube base situated atop the tank, extending 120±10mm into the oil, allowing precise temperature monitoring. Units in the 1000~2000KVA range feature an outdoor signal thermometer, providing accurate and trustworthy readings to maintain optimal operation.
Durable Transformer Tank Design
The transformer's tank showcases a corrugated wall, meticulously treated through a dust-spraying process to create a robust paint film. The corrugated heat sink effectively provides cooling and adapts to oil volume fluctuations due to temperature changes. This fully sealed design eliminates the need for an oil storage cabinet, reducing the transformer's height and maintaining moisture-free conditions through vacuum oil filling. For consistent peak functionality, regular oil sample tests are recommended.
