Title:
POLYMER BUSHING AND CABLE TERMINAL END CONNECTOR USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/036708
Kind Code:
A1
Abstract:
It is intended to achieve the weight reduction, sliming, and downsizing of bushings, commonality of types of bushings, and simplification of operating steps. A polymer bushing comprises a conductor draw-out bar (1) having a conductor insertion hole (1a) in the lower end, a hard insulation sleeve (2) installed around the outer periphery of the conductor draw-out bar (1), a polymer clad body (3) installed around the outer periphery of the insulation sleeve (2), and an electric field mitigation layer installed on the interface between the insulation sleeve (2) and the polymer clad body (3). The insulation sleeve (2) comprises a large-diameter insulation sleeve (2a) installed around the outer periphery of the lower region of the conductor draw-out bar (1), and a small-diameter insulation sleeve (2b) installed around the outer periphery of a portion of the conductor draw-out bar (1) excluding the front end. An embedment metal part (4) for electric field mitigation purposes is embedded in a portion of connection between the large- and small-diameter insulation sleeves (2a, 2b). Further, installed at the lower end of the large-diameter insulation sleeve (2a) is a cone-shaped receiving port (5) for receiving the stress cone (13) of a cable terminal (11), the receiving port (5) communicating with the conductor insertion hole (1a) in the conductor draw-out bar (1).
