The utility model provides a combined material transformer framework, includes the support column and sets up the insulating crossbeam on the support column, its characterized in that: the support column includes the combined material pipe, and insulating crossbeam is including the combined material pole that adopts the pultrusion preparation, crimping insulation umbrella skirt on the outer wall of combined material pole, the combined material pipe includes from interior stratum basale, strengthening layer, buffer layer and the skin that extremely sets gradually outward, the beneficial effects are that: the problem of current combined material to use when the transformer framework overall stability relatively poor is solved, the quality is light, intensity is high, stable in structure, transportation simple to operate are swift, corrosion -resistant, anti salt fog and acid rain, the electric property is excellent, and the operation is reliable, can reduce the support span by a wide margin, realize the compact and arrange, the later maintenance volume is few.
