1 BISG II Bus Insulator Squirrel Guard This new and improved isolation guard prevents animal-caused outages in electrical substation equipment. Reliable outage prevention: BISG II discs have been successfully eliminating outages from squirrels, raccoons, opossums, cats, and other animals in substations for years. The new BISG II guard has been designed to provide the same great protection with added features. Same high performance material: Superior high voltage outdoor materials are used in the new BSIG II guard design. The rugged, non-tracking, UV-resistant polymer ensures long-term performance even in the most extreme environmental conditions. Faster, easier installation: The BISG II guard allows easier hotstick installation by incorporating a threaded area in the guard. The integrated threads eliminate the need to hold a nut while installing the bolt assembly with a hotstick. The bolted design positively and tightly secures the device onto the insulator or bushing, eliminating loosening or drooping caused by wind, snow, ice, or animals. Expanded size range: The BISG II guard now fits insulator core diameters ranging from 1 (25mm) through 4.5 (115mm) from the factory. The new grill type design allows easy field modifications for even larger diameters (see your local Tyco Electronics representative for details). The BISG II guard can also have its outside diameter reduced by trimming along the grill ribs. This will allow the guard to fit in tight phase-to- phase insulator applications. Invisible appearance: The new BISG II design gives the same protection as the old guard without the noticeable profile. The invisible design allows easier visibility of switch blades and other equipment components through the guard.

9 R HVCE High Voltage Creepage Extenders A remedy for pollution flashovers of insulators

10 Raysulate High Voltage Creepage Extenders A remedy for pollution flashovers of insulators Raysulate Creepage Extenders increase the flashover performance of insulators by reducing the surface electric stress, reducing the leakage current and increasing the electric strength of the insulators. Installation of creepage extenders: Increases creepage length Improves insulator shape Adds high performance polymeric material to the creepage path Pollution flashovers Changing environments can cause increases in pollution levels which lead to excessive contamination of high voltage insulators. This may lead to unacceptably frequent flashovers if the creepage length and general design is inadequate. A replacement insulator having greater electric strength may be installed but the costs of this are high especially when a complete assembly, like a bushing, is involved. Common palliatives include live washing which reduces the contamination level, or surface treatments, either grease or rubbery coatings which smother the dirt or make the surface less wettable, or both. These palliatives have disadvantages in cost and effectiveness. The frequency of washing can be unacceptable and in some circumstances washing may promote flashover. Grease is a fire risk when it becomes choked with pollution and its removal is unpleasant and expensive. Coatings are difficult to apply and are also difficult to remove when eroded. The Raysulate Creepage Extender is a polymeric skirt internally coated with a specially formulated mastic. When heated the product shrinks around and bonds onto an existing insulator shed increasing the effective diameter and creepage distance of the insulator. Creepage extender design features needs only periodic inspection and will be effective many times longer than grease. Rugged Extenders are designed to be resistant to conventional spray washing techniques and will withstand all normal handling abuse and extreme weather conditions. Proven materials The extenders are fabricated using Raychem s unique high voltage materials technology which has over 25 years of high voltage field experience in adverse environments all over the world on cable terminations, insulators and bushings. Creepage extenders on 66 kv insulators Creepage extenders on 24 kv bushings Creepage extenders on 66 kv substation in a heavily polluted marine environment adjacent to a steelworks Increases creepage length This increases electric strength by reducing leakage current and surface stress. Improves insulator shape The increased shed diameter improves strike distance and improves heavy wetting performance by creating an umbrella effect. Bonds to insulator surface The extender adhesive has been specially formulated to strongly bond to the existing porcelain or glass skirt. Thus, the assembly

11 Simple to install Just degrease the insulator and shrink the extender with a gas torch or hot air gun. Raychem can provide installation training. Creepage extender testing Data from IEC 815 shows that at a fixed voltage, our typically recommanded extension of 20% to the creepage will more than double the pollution level needed to cause flashover (see figure 1). Pollution flashover tests (to IEC 507) on insulators fitted with creepage extenders show that, for a fixed salt concentration, flashover values increase in proportion to the increased creepage distance. Figure 2 shows typical results on a 66 kv post insulator. In practice, these results show that the addition of creepage extenders can effectively change an insulator which has marginal performance in the prevailing conditions to one which has a large margin of safety against pollution flashover. Tests have been done on a variety of insulator sizes and shapes including suspension and post insulators covering a range of diameters. The results consistently show an improvement for all insulators. Where the insulators are of a particularly bad design (eg. close packed sheds of identical size) the improvement in shape adds to the effect of the longer creepage path to give exceptionally good results. Raychem report UVR 8139 summarizes these results. Materials properties Raychem s high voltage insulating materials have undergone long-term field and laboratory testing to determine their suitability for use in the high voltage environment. The use of the material (eg. in several million Raychem high voltage cable terminations installed worldwide) bears out the excellent testing results and has helped establish an outstanding service record in the most severe environmental conditions. Tracking and erosion resistance testing On the ASTM D2303 inclined planetest, the material is non-tracking under all conditions including addition of 1% sugar contaminant. Resistance to weathering Raychem s on-going material tests measure the retention of elongation as a method of monitoring ageing. Retention of elongation is a good measure of resistance to cracking by UV light. The material properties measured for the Raychem high voltage material demonstrate its suitability for use outdoors even in extreme desert conditions where UV light concentrations are severe.

12 Selection table Creepage extenders are usually fitted to insulators with normal or alternating shed profiles (as defined by IEC 815). This IEC specification also categorises insulators into one of four pollution classes. We recommend moving from one class to a higher pollution class for improving flashover performance as shown in the table. Creepage extenders can also be used to produce extensions on insulators designed for highly polluted areas (with > 31 mm/kv as designed). For specific recommendation, contact your local Raychem representative. They can advise on fitting creepage extenders to non-standard shed profiles and pollution class insulators. Ordering information 1 XX denotes colour (01 = red) 2 On insulators close to the maximum diameter in the application range, the creepage extender will droop when installed. For further information, see the qualification report UVR The ordering unit of measure is pieces. Non standard sizes In many cases, creepage extenders for other sizes are available or can be designed. Contact your local Raychem representative for details.
