Technical Field

The utility model relates to a power equipment technical field specifically is a cable passes through ware.

Background

The electric submersible pump is used as a main artificial lifting mode of an offshore oil field, and an electric submersible cable is needed to convey power from the ground to the underground. When the oil-submersible cable passes through the wellhead device, the oil-submersible cable not only passes through the tubing hanger and the Christmas tree, but also cuts off the underground high pressure, so as to avoid the leakage of underground corrosive and flammable and explosive harmful gases, which causes production safety accidents. The penetrator is a main cable penetrating device of an offshore oilfield.

When the existing cable penetrator is used, the traditional rubber sealing effect is easily influenced due to the fact that the temperature born by a wellhead is high in the heat injection process.
