Performance
Operating Conditions
for sections, station OCS support structures, bearing suspension load, wind load and ice load.
Mechanical Performance
Standard test bending moments meet the TB/T 2286 class series; hot-dip galvanizing lasts at least 30 years and concrete pole crack resistance is type-tested.
Electrical Performance
with earthing terminal, meeting mast earthing and stray-current protection requirements.
Applications
Mainline sections:guyed steelanchor masts Gm350-250/15 are arranged by span and load on mainline sections.
Station throat areas:
guyed steelanchor masts Gm350-250/15 work with head-span beams in multi-track station areas.
Emergency repair:
guyed steelanchor masts Gm350-250/15 restore power supply quickly after storm-pole failures.
Corrosive environments:
guyed steelanchor masts Gm350-250/15 use thickened hot-dip galvanizing in coastal corrosive environments.
