This is a fully shielded, fully insulated medium-voltage flexible cable assembly designed specifically for connecting Voltage Transformers (PTs) to switchgear. It integrates a 630A European-style shielded connector on one end and an American-style PT elbow connector on the other, with a highly flexible EPDM cable in between. This "soft connection" solution simplifies installation in tight spaces, ensures complete sealing, and can be equipped with a surge arrester for integrated overvoltage protection.
The Shielded PT Cable Soft Connection FY-PQT-15/630 is a specialized, pre-assembled cable accessory engineered for optimizing connections inside Ring Main Units (RMUs), compact substations, and solid-insulated switchgear.
Its primary function is to provide a safe, reliable, and flexible link between a Voltage Transformer (PT) and the switchgear's busbar system. Traditionally, such connections require rigid busbars or field-assembled cables with complex insulation work. The FY-PQT-15/630 solves this by being a fully pre-tested, factory-molded assembly.
The following are key technical specifications for this model based on general industry standards for such products. Please confirm the exact figures with the official product test reports, as specific values may vary slightly based on cable length and connector configuration.
