With the continuous advancement of modern urban power grid construction, higher requirements have been put forward for the safety, environmental protection and energy saving of power distribution equipment. SC(B)10/11/12 series 10kV and 20kV epoxy resin cast dry-type transformers, with their excellent insulation performance, high mechanical strength and maintenance-free advantages, have become the core power distribution equipment in urban distribution networks, high-rise buildings and various important places. This article will provide a comprehensive analysis of the technical features, model evolution and application scenarios of this series of products.

Epoxy resin cast dry-type transformers have redefined the safety standards of power distribution equipment with their core capabilities of "oil-free, flame-retardant, self-extinguishing, and environmentally friendly." It not only solves the pain points of traditional transformers that are flammable, explosive, and prone to oil leakage, but also injects a steady stream of clean power into the power arteries of modern society with high reliability and low maintenance costs. As technology continues to iterate, it will play a more critical role in future smart grid construction.

In modern society, electricity is the blood that drives economic development and maintains daily operations, and distribution transformers are the indispensable "heart" of the power transmission network. As the world attaches increasing importance to energy conservation, emission reduction and environmental protection, the energy efficiency upgrade of traditional power equipment has become an inevitable trend. In this context, amorphous alloy distribution transformer (Amorphous Alloy Transformer) emerged as a revolutionary high-efficiency and energy-saving power equipment and is gradually becoming a "green pioneer" in the distribution network.

In the transmission and distribution network of modern power systems, double-winding OLTC oil-immersed power transformers are the core equipment to ensure voltage quality and power supply continuity. It combines the three major advantages of "simple double winding structure", "excellent oil-immersed heat dissipation" and "on-load voltage regulation without power interruption", and is widely used in substations, industrial and mining enterprises and new energy stations. This article will systematically elaborate on its definition, structure, principles, characteristics and applications.

In the field of traditional power transformers, the laminated core structure has been used for hundreds of years, but its shortcomings such as discontinuous magnetic circuits, unbalanced three-phases, and large amounts of consumables have become increasingly prominent. With the advancement of the global "dual carbon" strategy and the energy efficiency upgrade of distribution networks, three-dimensional wound core transformers are becoming the mainstream choice for a new generation of energy-saving transformers due to magnetic circuit optimization and structural innovation. This article will give you a comprehensive understanding of this product from the structural principles, core advantages, comparative analysis and application scenarios.

The JXF control box is equipped with multiple protection functions including overload protection, short-circuit protection, phase loss protection, pump water leakage protection, motor over-temperature protection and electric leakage protection, as well as complete status display functions. It supports single-pump and multi-pump control modes, multiple main and standby pump switching methods and various starting modes. It is widely applicable to automatic control scenarios such as water supply, drainage, fire protection, spray pipe network pressurization, and HVAC cold and hot water circulation in agricultural production and various buildings.
