Support: malleable cast iron / hot dip galvanized
Body, keeper: aluminium alloy
Connecting bolt: type S, DIN 48 073, steel grade 8.8 / hot dip galvanized, cotter pin A2
Screws: stainless steel A2-70
Washers: steel 200 HV, A2
These earth wire supports with movable trough are used for straight cable routing to attach the earth wire. The earth wire supports are intended for attaching aluminium/earth ropes to the suspension tower.
For angled suspension tower (one-sided deflection), the C earth wire supports are provided, whereby suspension clamps must be used to suspend the earth wire.
For large cable deflections due to wind on suspension tower (two-sided deflection), C-earth wire supports are used.
The earth wire is also suspended using suspension clamps.

Additional informationThese adapters are installed for compensating the distance of removed post insulators MST 212 (applied at carrier-frequency telephony by earth wires) to keep the same sag for the earth wire. The adapters are furnished with a kit of bolts M16 x 50 (h.d.g.), packed in a foil bag.
Plate: steel/ hot dip galvanized
Threaded bolt: steel grade 5.6/ hot dip galvanized
Nuts: steel grade 10/ hot dip galvanized
Lock washers: stainless steel A2
Washers: steel 200 HV/ hot dip galvanized
These adapter plates are used for installing earth wire supports (except C-shaped supports) if the attachment hole spacings of earth wire support and tower are different. They are not suitable to attach earth wire tension supports. The nuts are to be tightened with an installation torque of 38 Nm (at M12), 90 Nm (at M16).
Insulating plate: resinoid compound
Washer: steel / hot dip galvanized
Insulating bushing: resinoid compound
Intermediate ring: copper-leather
The insulating sets are used in conjunction with earth wire supports for the insulated installation of earth wires. Before installing, the contact mounting face on the tower has to be cleaned.
The bridging of the insulating set required in normal operation is carried out with earthing straps (according to sheet B135/13).
These must be ordered separately.
(Application for earth wire supports according to sheet B131/1, B131/5)
For insulated earth wire installation, the insulating set in this catalogue sheet must be used to attach the earth wire supports to the support mast. The bridging of the insulating set is bridged with earthing straps in accordance with the sheet Earthing straps for insulated earth wire supports.
