HYTGJ-15/200 casing well is mainly used in 200A high voltage lead wires of American box transformers, ring network cabinets or other electrical equipment. It is suitable for transformer oil medium. It adopts special non-leakage technology and can be connected to single-pass or double-pass sleeves. tube. The copper bolts of the cased well are of two separable sections. If the connecting bolts are damaged when the single-pass casing (or double-flux magnetic tube) is installed, only the bolts need to be replaced, which shortens the installation time and improves work efficiency.

200A extended cased wells are widely used in SF6 ring network cabinets and dry box transformer outlets, and are used in conjunction with 200A single-pass casing or double-pass casing. The structure is more reasonable and the performance is more reliable.
