    摘要： A high voltage bushing is formed from a plurality of insulating layers. Conductive layers are interleaved with the insulating layers, and are electrically insulated from each other. The ends of the conductive layers are overlapped by stress grading layers, to minimise the electrical stress on the bushing.

    摘要： An arrangement for and method of limiting the electrical stress in a region of high electric field strength associated with high voltage equipment, especially power cables, employs two overlapping layers of semiconductive material that have different a.c. electrical impedance characteristicsto surround the region. The inner layer may be a heat-shrinkable tube having a linear characteristic, and the outer layer may have a non-linear characteristic and be provided as an internal coating on a further heat-shrinkable tube of insulating material. Such an arrangement provides good electrical protection in terms of both a.c. and impulse performance.

    摘要： The invention provides an L-shaped connector for connecting a high voltage electric cable to a bushing of a transformer, switchgear, or other electrical apparatus. A first arm of the connector is tapered to be a push-fit on to the bushing, and the other arm has a heat-shrinkable tubing integral therewith for receiving, and sealing on to, a stripped cable. Electrical connection to the cable is made completely within the insulating body of the connector, by a screw-threaded pin that is accessed through the first arm of the connector.
