FIELD: electricity.SUBSTANCE: in field communications cable with improved sealing there are current-carrying conductors, protective and insulating sheath and a load-carrying element placed under the above sheath. Connective half-couplings are set at each side of the cable factory length. Each of the above half-couplings comprise a body, a terminal block with soldered cable conductors is placed at one side of the body while at the other side of the body there is a cable input unit interacting with external surface of the body. The cable input unit consists of a tail nut, one or several sealing elements and washers. At that inner cavity is available in one of the sealing elements at the cable input unit. Besides, at the washer placed directly in front of this sealing element from the cable input side there are axial through openings communicating with the inner cavity of the sealing element.EFFECT: improving reliability of the field cable during its long-term operation.2 cl, 5 dwg |
