SEALING PRODUCT AND METHOD FOR SEALING LIQUID-CONTAINING CABLES Russian patent published in 2012 - IPC H02G15/18 

FIELD: electricity.

SUBSTANCE: sealing device is intended for design of cables intended for underground usage. The pressure-limiting device for cables may contain, for example, the first cable including a conductor and an oil-containing layer encapsulating the conductor and the second cable having a conductor. At the connection spot the first cable conductor may be connected to that of the second cable. The connection spot and the conductors of the first and the second cables may be covered with a pressure-limiting hose. Installed at multiple spots o the pressure-limiting hose may be multiple ties for crimping the pressure-limiting hose round the connection spots and the first and he second cables sections. The pressure-limiting device may be implemented in the form of a hose on a single-strand cable or in the form of a breakout with individual hoses on a multi-strand cable such as a three-strand cable.

EFFECT: oil-containing cables sealing improvement.
