Support tie are mainly two types: 1.Top ties: fix the insulated conductor on the top groove of the insulator. 2.Side ties: fix the insulated conductor on the side groove of the insulator.
Material of Twin Support Tie
High elasticity PVC,it can effectively prevent the insulated conductors from slipping out of the insulators during operation.
