Wire wound resistors are usually wound on a rod-like ceramic insulating substrate or other insulating substrates. The resistance wire is an alloy material such as nickel chromium or manganese copper, and the two ends of the resistance wire are connected with fixed pins. The resistance wire is usually coated with non-conductive paint, and the periphery is packaged with different packaging materials (such as aluminum shell packaging). The winding resistance of aluminum shell package is very common at present, and its heat dissipation ability is very strong, so it is generally suitable for high- power applications. There is also a familiar ceramic package winding resistance, we are more used to call it cement resistance, but not the former is used frequently.
■ About Main Contact VoltageThe parameters of DC contactors are the core basis for selection, installation, and safe operation, covering three key dimensions: electrical performance, operating characteristics, and safety protection.
Seal DC contactors are the go-to choice for many industrial vehicles. This is primarily due to their superior quality, durability, and reliability. These contactors are designed to meet the specific needs of industrial vehicles, ensuring optimal performance and longevity. In this article, we will ex
Introduction to tho three types based on their coil control methods: single-coil control, dual-coil control, and energy-saving board control (i.e., PWM control board + single-coil control). This article compares the structure, working principle, and energy consumption characteristics of DC contactor
The application of high-voltage DC contactor products is becoming increasingly widespread with the development of electrification and new energy industries. And the products related to numerous application industries which have different requirements on voltages and powers. In practical applications
Power resistors are used to withstand and consume large amounts of power, and they are made of materials with high thermal conductivity for efficient cooling. They are usually designed to be coupled to a heat sink in order to be able to consume a large amount of power. For precharged resistors.
