Most of the Power Industries has experienced unwanted disruptions due to unplanned outages of one type or another. These have traditionally been classified as Weather, Wildlife or Unknown, with limited knowledge of the proportions due to each. Now, with greater knowledge, such unexpected outages are better categorized as caused by...
Wildlife (Birds / Animals)
Weather (Storms / Wind / Lightning)
Vegetation (Tree Branches)
Human Intervention (Accidental / Deliberate)
Over the past 20 years, there has been increasing realization that the uncontrollable external impact of wildlife is responsible for a far greater proportion of unplanned outages than previously acknowledged.
How are they being Electrocuted?
Broadly speaking, problems created by wildlife at substations and on overhead lines fall into one of two main categories: bridging and wildlife guano pollution flashover.
Bridging is where a bird or animal makes contact between phases or between phase and ground, leading to a short circuit. For example, large birds can easily cause problems across all distribution voltages at substations and on lines. Phase bridging usually results in the creature being electrocuted.
Animals are electrocuted by touching the hot clamp, cables, fuse cutout, lightning arrestor, primary input (bushings), or secondary output (terminals and wires) on uninsulated power transformers.
Types of injures are caused by Electrocution due to Substations & Transformers
Death
Electrical Burns
Heat Burns From Catching on Fire
Limb Amputations
Fatal Injuries to Internal Organs & Unborn Infants
Unconsciousness
Concussion (From Falls)
Broken Bones (From Falls)
Solution to Prevent Wildlife Electrocution
Several factors are driving growing interest in applying wildlife protective devices at vulnerable substations. Industry sources claim that such risk at substations could be reduced by 80 per cent through selective application of well-designed wildlife protection products.
Wildlife protection devices being offered have different designs and are made from a variety of polymeric materials. One of the keys to good performance is fit. Since power arcs travel through air, the gap between creature and live fitting is critical. Any crack or seam in a protective covering could allow the arc through and the higher the voltage the greater this risk.
One of the considerations when it comes to composition of materials used in these products is suitability to an outdoor environment of electric field and persistent high UV. Materials must be inert and resistant to tracking and erosion since they will face the same stresses as insulators.
Solution to Prevent Wildlife Electrocution Substations & Transformers
We offer PVC Material for Voltage up to 36kV
We offer Silicone Material Insulation for Voltage above 36kV
Easy and fast to install, no special tools or heat needed
Our products are made from quality PVC or Silicone Material. They are Easy and fast to install, no special tools or heat needed. The material used has Outstanding weathering, UV, Ozone, chemicals, fungi resistance. They are Low cost compared to the damage to the substation and easy for maintenance, and reusable. It has excellent thermal & electrical properties. Cover prevent short circuit resulted from birds, insects or foreign objects lapping and protect power distribution outer insulation. Insulating covers can eliminate animal caused outages on breakers, transformers and pole-top bushings ranging 15 kV to 110 kV.
Protecting Wildlife and Minimizing Outages
Wildlife caused power outages, has been costing huge amounts for the Power transmission companies. Shine Industries employs proven techniques and invests in animal-deterrent technology to keep animals out of the transformers and substations. To install the disks, bushing covers and line covers, the safest way to install the materials is when everything is de-energized and grounded. So that they can work on it with bare hands, clip, snap or slip the material in place, and then re-energize the line or circuit.
