DSS Switch OLTC Directional Sequence Switch
DSS Switch OLTC Directional Sequence Switch is a precision engineered control component used in On Load Tap Changer (OLTC) systems of power and distribution transformers for accurate directional sequence operation during tap changing. Manufactured using high grade insulating and conductive materials, the DSS switch ensures reliable switching sequence, smooth transition control, and safe operation under demanding electrical conditions. It is widely used in transformer control circuits to maintain proper tap changer movement direction and sequence synchronization in automatic voltage regulation systems.
Our OLTC DSS switches are designed for high mechanical durability, excellent contact reliability, low maintenance, and long operational life. These switches are suitable for indoor and outdoor transformer applications and are compatible with various OLTC mechanisms used in power utilities, electrical substations, transformer manufacturers, EPC contractors, and industrial power systems. The robust construction ensures stable performance under vibration, temperature variation, and continuous operation conditions.
The Directional Sequence Switch for OLTC applications is available in multiple contact configurations and customized designs as per transformer specifications and control panel requirements. Each DSS switch undergoes strict quality inspection and electrical testing to ensure dependable performance and operational safety. The compact design allows easy installation in transformer marshalling boxes, OLTC drive mechanisms, and control cabinets.
