Dry OLTC is an oil-free on-load tap changer used to adjust the output voltage by changing the effective number of turns of the transformer winding when the transformer is running under load. This device allows voltage regulation without interrupting the power supply, thereby improving the flexibility and stability of the power system. The dry OLTC adopts an oil-free design, which avoids the problems of oil leakage and pollution that may exist in oil-immersed equipment, and improves the reliability and environmental protection of the equipment. OLTC can adjust the voltage when the transformer is running under load without interrupting the power supply, ensuring the continuous and stable operation of the power system. The dry OLTC has been carefully designed and manufactured, with high reliability and durability, and can operate stably in various harsh environments. Modern dry OLTCs are usually equipped with intelligent control systems, which can realize functions such as remote monitoring, fault diagnosis and automatic adjustment, and improve the intelligence level of the equipment. Dry OLTC is widely used in power systems, renewable energy, high-voltage direct current transmission and other fields. With the growth of global electricity demand and the development of renewable energy, the dry OLTC market will continue to expand.
