Description
Technical Field
The utility model relates to a cold contraction formula cable outdoor termination.
Background
In many cases, power is transmitted through cables located outdoors, often at voltages in excess of 50KV in order to reduce power losses caused by electrical resistance in the cable, and to terminate the cable, a transition must be connected between the cable conductor and ground, which transition must be able to withstand the voltage drop between the cable conductor and ground, these transitions being commonly referred to as "terminations". Due to the high voltage of the cable, and the fact that the cable and the termination are located outdoors, the termination is subject to electrical and environmental stresses including water, dust, snow, wind and temperature fluctuations, which are generally caused by the termination itself and include high electrical field strength, leakage currents ("leakage"), and flashovers.
In general, when the outdoor cable terminal is installed, the second part of the outdoor cable terminal, which serves as a stress cone, faces downwards, and the umbrella skirt on the traditional outdoor terminal can play the roles of water resistance, dust resistance and snow resistance. However, in some special cases, the outdoor terminal of the cable is reversely installed, and at this time, the skirt cannot play the roles of water resistance, dust resistance and snow resistance, and is a part for accumulating water, dust and snow. In addition, the outdoor terminal is easy to cause stress reduction due to long-term thermal expansion and contraction, and the cable cannot be effectively protected.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a cold shrink formula cable outdoor termination and cable of reverse installation.
In order to solve the problem, the utility model discloses a technical scheme including being columniform first portion and playing the second portion that stress cone acted on, the pressure injection molding has stress cone conducting layer in the second portion, first portion, second portion center are equipped with the through-hole that the power supply cable passed, longitudinal extension has interval arrangement's full skirt on first portion, the second portion, first portion, second portion and full skirt integrated into one piece, the terminal surface that the full skirt corresponds the second part direction is the conical surface.
The outdoor terminal of the cold-shrinkable cable is characterized in that: and the inner wall of the second part is molded with a conductive rubber layer by pressure injection.
The outdoor terminal of the cold-shrinkable cable is characterized in that: the lower end of the first part is provided with a first reinforcing rib, and the upper end of the second part is provided with a second reinforcing rib.
The outdoor terminal of the cold-shrinkable cable is characterized in that: and the side surface of the first part is provided with a third reinforcing rib.
The outdoor terminal of the cold-shrinkable cable is characterized in that: the umbrella skirt is arranged in a size interval.
The outdoor terminal of the cold-shrinkable cable is characterized in that: the umbrella skirt is formed by arranging a group of large umbrella skirts and small umbrella skirts at intervals.
The outdoor terminal of the cold-shrinkable cable is characterized in that: and the lower end of the stress cone conducting layer is provided with a horn mouth.
A cable comprising a cable body, characterized in that: the cable body is sleeved with the cold-shrinkable outdoor cable terminal.
The utility model discloses a cold contraction formula cable outdoor termination and cable advantage as follows: the reverse installation of outdoor terminal of cable has been realized, promptly the second part direction can be up, simultaneously the full skirt has reverse creepage and plays waterproof, dust proof, snow proof's effect.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a cross-sectional view of the outdoor terminal of the inventive cold-shrink cable;
fig. 2 is the utility model discloses the cover has the cable cross-sectional view at the outdoor terminal of cold shrink formula cable.
Detailed Description
As shown in fig. 1, the utility model discloses a cold-shrinkable cable outdoor termination, including being columniform first portion 1 and second portion 2 that plays the effect of stress cone, the injection moulding has stress cone conducting layer in the second portion, first portion 1, the 2 centers of second portion are equipped with the through-hole 13 that supplies the cable to pass, longitudinal extension has interval arrangement's full skirt 3 on first portion 1, the 2 upper longitudinal extensions of second portion, first portion 1, second portion 2 and full skirt 3 are by insulating rubber integrated into one piece, the terminal surface that full skirt 3 corresponds 2 directions of second portion is conical surface 4.
Furthermore, a first reinforcing rib 6 is arranged at the lower end part of the first part 1, and a second reinforcing rib 7 is arranged at the upper end part of the second part 2. The first part 1 is flanked by third ribs 8. By arranging the reinforcing ribs, the problem of stress reduction caused by long-term expansion with heat and contraction with cold is solved.
Furthermore, the umbrella skirt 3 is formed by arranging a group of large umbrella skirts 9 and small umbrella skirts 10 at intervals. Further improving the capability of preventing water accumulation, dust accumulation and snow accumulation.
Furthermore, the lower end of the stress cone conducting layer 5 is provided with a horn mouth 11, and the penetration of a cable is easier by arranging the horn mouth 11.
