Product descriptions from the supplier

Description

Working humidity range: At a maximum temperature of 40℃, the relative humidity does not exceed 50%. At a maximum temperature of 20℃, the relative humidity should not exceed 90%. 2. Normal operating temperature range: -5℃ to 40℃. Permissible temperature range: -40℃ to 80℃. 3. Altitude: no more than 2000m. When the altitude exceeds this value: 1) The temperature rise of the fuse increases by about 0.5k for every 100 meters above sea level. 2) For every 100 meters of elevation increase, the ambient temperature decreases by about 0.5 ℃ on average. 3) Under normal circumstances, fuses used in open environments can ignore the effect of altitude on rated current and still be selected in accordance with standard conditions. 4) For fuses used in closed environments, if the ambient air temperature of the box or the temperature inside the box does not decrease signiffcantly with the elevation, it can still reach more than 40℃, it is necessary to reduce the rated current capacity.

    Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr

  • Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?
    Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I

    What is a Rectifier Transformer?"Power conversion" is a general term encompassing rectification, inversion, and frequency conversion, with rectification being the most widely used among them. Rectifier equipment converts input AC power into DC output through rectification and filtering. A rectifier transformer serves as the power supply transformer for such rectifier equipment. In industrial applications, most DC power supplies are obtained by combining a rectifier transformer with rectifier equ
