Rectangular Cable Assemblies are widely used in a variety of applications, from manufacturing, transportation, security to military. The H3DDH-5018M cable assembly is one such product that is specifically designed to provide reliable performance and robustness in harsh environments.The H3DDH-5018M is composed of two separate cables, a center metric and a secondary cable, that are designed to work together in order to provide the same performance as a single cable. The center metric is a highly reliable and robust cable that features a cross-linked polymer insulated core which allows for higher power handling capabilities. The secondary cable features a silicone insulation which allows for greater flexibility and increased signal integrity.The primary application for the H3DDH-5018M is in the field of high-voltage power transmission. It is designed to handle voltages up to 2,500 volts and is capable of transmitting up to 1,000 amps of power. The cable assembly is also suitable for use in signal and data transmission, as well as for providing robust grounding in harsh environments.The H3DDH-5018M is designed to handle a wide range of frequencies and can be used in different signal types such as CAT5, ethernet, and coaxial cables. The cable assembly features an oil-sealed stainless steel sleeve which helps protect the cable from environmental elements, such as moisture and dust, as well as providing EMI/RFI protection. This allows the cable assembly to be used in a variety of applications, including vertical lift systems, emergency broadcast systems, audio applications, and communications networks.The working principle of the H3DDH-5018M is to transfer current from a source to a destination via the central and secondary cables. The two cables act as a single unit, where the central cable carries the electrical current to the destination and the secondary cable acts as a return path, allowing the current to travel back to the original source. This design ensures a reliable and robust connection, allowing for greater current levels to be transmitted in harsh environments.In conclusion, the H3DDH-5018M cable assembly is an ideal solution for a variety of high-voltage power and signal transmission applications. It is designed to be reliable and robust in harsh environments, while offering excellent EMI/RFI protection. It also offers a wide range of frequencies and signal types, making it a versatile product for a multitude of applications.
