Mengapa tidak kabel yang disejukkan dengan air leak?
Banyak peranti akan menjadi panas setelah lama digunakan, bahkan kabel. Sekiranya arus besar, mereka akan mudah memanas. Kejadian haba akan mempengaruhi operasi dan jangka hayat yang normal. Kabel yang disejukkan dengan air adalah sejenis kabel yang menggunakan air untuk menyejukkan. Kerana masalah penjanaan haba yang diselesaikan, kekuatan dan kapasiti kabel pendingin air jauh lebih tinggi daripada kabel biasa. Kita semua tahu bahawa air yang kita lihat setiap hari adalah konduktif, jadi mengapa kabel pendingin air tidak bocor? Apakah prinsip kabel yang disejukkan dengan air?
Water-cooled cable is a new type of cable. The main feature is hollow water-through. It is generally a special cable used in high-current heating equipment for medium-frequency and power-frequency high-current transmission. It is usually composed of three parts: outer sheath, wire and electrode, which is also the cable head. For ordinary water-cooled cables, the electrodes are welded using copper tubes and copper bars, which are not closely connected to the equipment. The wires are twisted with bare copper wires and have a large bending radius. The outer protective casing uses ordinary rubber hoses, which have low pressure resistance. The casing and the electrode are fastened by ordinary clamps, and the airtightness is not very good, and water leakage is relatively easy. Therefore, do not use water-cooled cables that are of poor quality. For water-cooled cables, the electrodes are made of integral copper rods by turning and milling, and the surface has been passivated or tinned. The wire uses tinned copper stranded wire, or enameled wire, which is woven by a CNC winding machine, with a small bending radius and high flexibility. The outer sheath is a synthetic rubber tube with a reinforced interlayer, which has high pressure resistance. Between the casing and the electrode is the used copper clamp, which is fastened by professional equipment cold extrusion, and has good sealing performance and is not easy to leak. Therefore, the use of water-cooled cables is more safe and secure.
