Our hybrid system
is unbeatable.

Overhead line masts.

Combination of the best properties.

Hybrid elec­tri­ci­ty pylons in the over­head line area have seve­ral advan­ta­ges:

If the mate­ri­als steel and GRP are com­bi­ned to form a pylon for power lines, tog­e­ther they can with­stand wind and wea­ther, elec­tric shocks and rodents.

Steel and GRP also offer no oppor­tu­ni­ties for insect infe­sta­ti­on, wild­life dama­ge or rot.

Robust

The hybrid mast has high strength and low deflec­tion with a com­pa­ra­tively low weight. Even under extre­me wea­ther con­di­ti­ons, it beha­ves extre­me­ly well, late­ral vibra­ti­ons and ice-indu­ced gal­lo­ping are not an issue. Elec­tric shocks are avo­ided thanks to the high dielec­tric strength / insu­la­ting pro­per­ties of the GRP attach­ment. Steel and GRP offer no oppor­tu­ni­ties for insect infe­sta­ti­on, wild­life dama­ge or rot.

Flexible

The GRP upper sec­tion can be fle­xi­bly pro­vi­ded with holes and reces­ses in the fac­to­ry or on site. Exis­ting attach­ments such as cross­bars, clamps and slee­ves can be used. The pole cavi­ty is ide­al for safe­ly accom­mo­da­ting cables and eart­hing in the pole. The con­nec­tion bet­ween the steel and GRP part ensu­res a struc­tu­ral ele­ment that yields in the event of an extre­me event. In the event of a tree col­lap­se, for exam­p­le, the upper sec­tion is detached and can be easi­ly repla­ced, while the steel lower sec­tion remains in place.

Animal welfare

The cur­rent-insu­la­ting GRP top sec­tion pro­tects landing and res­t­ing birds and com­pli­es with the strict Ger­man appli­ca­ti­on rules for bird pro­tec­tion on medi­um-vol­ta­ge over­head lines (VDE-AR‑N 4210–11). A spe­cial bird perch on the cross­bar pro­tects the birds if the pha­se spa­cing is small.
