Fiberglass insulation rod known Pulling. By the company's own R & D success of "triangular telescopic fully insulated operating rod" by the cross section of a hollow triangular high dielectric strength epoxy fiberglass and part of the insulating member is made. Triangular cross-section of the glass tube, the use of E-glass fiber braided reinforced Baptist pure epoxy, high temperature pultrusion made of high mechanical strength, high dielectric strength, high temperature. Retractable high pressure Pulling generally up to do six meters, light weight, small size, easy to carry, easy to use, scalable, navigate to any length according to the use of space, effectively overcome the interface style Pulling due to the use of fixed-length inconvenient shortcomings, this product has applied for national patents. Features: high strength, high insulation, high temperature, light weight. Electrical performance: with 600mm of insulation rod pressure to play at a voltage of 150KV, it is possible for 1 minute without breakdown. Various types of wind up bar can be customized according to user requirements
