    Abstract: The promotion and application of composite material insulating crossbar are in favor of solving the problem of lightning stroke disconnection caused by the inductive thunder. This paper expounded the "10 kV overhead insulated wire insulation crossbar typical arrangement". Introduction was made to the achievement of typical design. This paper made clear the applied arrangement and wire selection and usage of elevation, weather zone, pole type and so on, enriched the pole head arrangement form, improved the insulation coordination and lightning protection grounding mode, summed up the crossbar structure style, serialized the size of the crossbar and solved the insulation crossbar downlead arrangement, which enhances the lightning withstand level of 10 kV overhead line, especially provides the safeguard for avoiding the tripping and disconnection caused by the inductive thunder lightning stroke.
    Key words: insulation crossbar; typical design; pole and tower; lightning stroke
