The outdoor oil-immersed transformers at 10kV, 20kV, and 35kV levels have an advanced design with improved performance characteristics. They feature a unique structure with three core columns arranged in an equilateral triangle configuration. These gaps within the magnetic circuit, along with a core column loss, help reduce noise levels and ensure better balance of the transformer components. Additionally, these transformers effectively minimize the presence of the third harmonic component. They are suitable for various applications, including urban and rural areas, industrial and mining power grids, and are particularly well-suited for combination transformers and pre-installed substations.

36KV Centre-break Two Post Isolating Switch is crafted from high-strength porcelain, which enhances the product's stability, reliability, and strength density. This material formulation minimizes strength variation and boosts the product's tensile strength. The structural layout includes a significant margin of strength, ensuring the product's operational stability and dependability.

This circuit breaker is a multifunctional low-voltage protection device designed for distribution systems with AC 50Hz, rated voltage below 400V, and rated current below 63A. It is suitable for industrial, commercial, and civilian power networks. Its core functions integrate security protection, equipment protection, and intelligent monitoring, which can significantly improve the reliability and operation efficiency of the distribution system. Core functional highlights: 1. Safety protection 1) Personal safety assurance: Through high-precision residual current detection technology (RCD), indirect contact protection is provided, effectively reducing the risk of electric shock. 2) Equipment and line protection: Integrated overload and short circuit dual protection mechanism, accurately cutting off fault current, avoiding electrical fires and equipment damage. 2. Intelligent monitoring and early warning 1) Leakage pre-alarm function: Real-time monitoring of residual current in the circuit. When abnormal leakage (such as insulation degradation) is detected, an alarm signal is output through a passive normally open contact (dry contact). It can be linked to SCADA, fire protection system or sound and light alarm device without an external power supply to achieve early warning of faults and ensure power supply continuity. 2) Flexible threshold configuration: supports custom setting of leakage alarm values, adapting to sensitivity requirements of different scenarios (such as 30mA/100mA adjustable). 3. Diversified control ability Line and motor control: suitable for occasional switching operations of distribution lines or intermittent start-stop control of small motors, meeting the requirements of nonfrequent operation scenarios. Typical application scenarios: 1) Key power supply areas: places with high requirements for power continuity, such as data centers and hospital IT systems, have alarm nontrip mechanisms to avoid accidental power outages. 2) Equipment protection: Front-end protection for devices such as frequency converters and outdoor electrical cabinets that are susceptible to electrical leakage or environmental impact. 3) Intelligent operation and maintenance: By connecting to the building management system (BMS) through touch signals, remote monitoring and preventive maintenance can be achieved. Product advantages: 1) High reliability: thermal magnetic double trip structure, balancing overload delay protection and short-circuit instantaneous action characteristics. 2) Flexible expansion: an optional communication module, supporting remote status monitoring and fault diagnosis. 3) Easy installation: Standardized modular design, compatible with mainstream rail installation, suitable for compact distribution boxes. Summary: This circuit breaker is designed with the concept of "warning first, safety oriented", which ensures the safety of personnel and equipment while maximizing the stability of system operation. It is the preferred protective device for modern intelligent distribution systems.

The S-M series three-phase oil-immersed transformer is not just robust, it's also a game-changer in terms of efficiency and energy savings. Its fully sealed and oil-filled corrugated tank allows for thermal expansion and efficient heat dissipation, while the innovative insulation provides enhanced protection against short circuits. The windings are crafted from arranged in a multi-layer cylindrical configuration, and all fasteners are treated to prevent loosening. This transformer's exceptional efficiency and minimal energy losses mean potential significant power consumption reduction, a feature that has made it a staple in various industries, including power generation, transmission, and distribution, as well as industrial, mining, and transportation applications.

Outdoor transformer oil immersed transformer 10kv 20kv 35kv are a newer type of transformer that boasts a better-designed structure and improved performance. Its three core columns, arranged in an equilateral triangle shape, eliminate any air gaps in the magnetic circuit, resulting in tighter windings. The length of the three magnetic circuits is consistent and shorter, and the cross-sectional area of the core columns is closer to a circle. These design improvements lead to enhanced performance, reduced loss, decreased noise, and a better balance of the three components. Additionally, the third harmonic component is reduced. This transformer is well-suited for use in urban and rural areas, industrial and mining enterprise power grids, and is ideal for combination transformers and pre-installed substations.
