Landscaping around electrical equipment

Transcription

1 Landscaping around electrical equipment Electrical equipment and natural gas lines are a part of every home s landscaping. Whether these are visible, such as an overhead powerline or a padmount transformer, or hidden, like buried electrical or natural gas lines, they should be taken into consideration before any landscaping is done. If you plan to excavate on your property in order to plant trees or build a fence, remember to call Manitoba Hydro before you dig. Striking buried electrical or natural gas equipment can result in serious injury. By calling before you dig, you prevent damage and save the costs of unnecessary repairs, which you may be liable for. More importantly, your call will prevent loss of life, injury, environmental pollution, equipment damage, product losses and service outages. If you are outside of Winnipeg, call Manitoba Hydro at MB HYDRO ( ) or in Winnipeg call Manitoba Hydro will arrange to have trained personnel visit your property and mark the locations of underground electrical and natural gas lines as well as vaults containing transformers or electrical switchgear. During peak construction from April to October, please call one to two weeks prior to your planned excavation. The remainder of the year, please allow two working days notice to locate lines on your property. You should also be aware of any overhead powerlines in your yard if you will be working with oversize equipment. Any contact with overhead powerlines could be dangerous. A tree that comes into contact with a powerline can be energized, creating a hazard for people at ground level. To prevent these hazards, property owners are encouraged to plant trees that will not cause a problem down the road. Keep all plantings to a minimum of two metres back from the powerline, and plant taller growing trees such as willow, ash, maple or evergreen trees at least six metres back from the powerline. If these trees are closer, they will ultimately require continued trimming and maintenance. Consider planting low-growing shrubs that will attract attention to your yard and away from overhead lines. For more information on safe landscaping near powerlines, contact your local Manitoba Hydro district office or check our website at Padmount transformers Many homeowners have padmount electrical transformers located on their property.
