Overhead Line Insulation Sleeve

Product Details

Gala Insulation Enhancement Products such as Heat Shrinkable Tubes, Tapes, Sheets, Pre-moulded Protection Covers, etc. provide a long term, cost effective and easy to install retrofit solution to eliminate power outages caused by bird and animals. Electrical Distribution equipment with bare bus bars, conductors and connections is always at risk to having phases or phase to ground accidentally bridged. As well as the obvious problems caused to the network, such events can also endanger protected wildlife. Birds and animals often enter substations and interfere with overhead lines causing faults by bridging air clearances. Substation equipment is vulnerable to flashovers caused by accidental bridging of phases, or phase to earth. Usually made by birds, animals, vegetation or airborne debris, flashovers can be very expensive in terms of damage to equipment, reduced reliability and in some cases even electrocution of protected species. Almost any event of this nature can be prevented by insulating the strategically vulnerable bare metalwork with a combination of Gala Insulation Enhancement Products.Insulcover is a Wrap Around Line Cover that provides retrofit insulation for Overhead Conductors to help prevent electrical outages caused by trees or wildlife coming into the contact with distribution lines. It is manufactured from high quality Non-tracking Cross-linked Polyolefin material. Gala Overhead Line Covers can be used in many applications upto 66 kV. her resistant v Tracking & Erosion resistant v Prevent Conductor from Chemical corrosion effected by strong acid, alkali, salt, etc. v Halogen free v Insulcover is available in four sizes that covers conductors up to 800 sq. mm. v GOC comes with Mastic for high voltage applications Technical Specification* Selection Chart: Gala Conductor Size Conductor Size Packaging Code Sq. mm. in Dia.
