The Single Insulation Bracket Support Insulator is an electrical insulation product that is installed on a power system to support the conductors and at the same time provide electrical isolation from earthed objects. This type of insulator is mainly formed of one insulating component which is made from composite polymers for mechanical and electric load bearing. It has only one insulating element and is therefore more compact and cheaper than double-insulated insulators, but still suitable for applications in which a somewhat lower level of insulation is adequate. This insulator is widely employed in electrical power transmission and distribution utilities to support conductors on poles or towers; it makes certain that conductors remain securely in position while being electrically separated from the support structure. Wishpower has consistently focused on the production research and development of composite insulators for more than 20 years, providing you with the most professional products and solutions.
Single insulation insulator designs are usually preferred because of the lower cost of producing these items in terms of material and assembly. This makes them desirable in all those applications where cost stands as a critical consideration without necessarily having to sacrifice primary performance.
This single insulation structure will lead to a compact and light overall design will also save on more space and is easy to install. This is especially so in installations where space is at a premium, or in structures, where weight is a consideration.
With fewer components, it requires less maintenance. The simpler design also means that inspections and repairs are more straightforward, reducing downtime and maintenance costs.
In scenarios where high levels of insulation are not necessary, it provides an adequate and reliable solution, avoiding the overengineering and extra costs associated with double insulation models.
Fewer numbers of parts are used in single insulator bracket construction which in turn leads to less time in assembling the unit and therefore is less prone to assembling errors.
As these insulators contain only one insulating element, they are relatively lighter and can be transported and handled more easily than heavier equates in hard terrains or regions that are remote.
With a simpler design, there are fewer points of potential failure, reducing the overall risk of insulation breakdown and improving the reliability of the system over time.
The reduced transformation losses of leakage currents keep power losses to a minimum, enhancing the efficiency of the power distribution system.
In urban areas where space is a real limitation, the single insulation support isolator is specifically suited for POLE-MOUNTED or to fit in a small space between buildings while striving to deliver optimum power safety.
As shown when used to send power lines in rural areas where distances to be covered are rather long, such insulators reduce weight hence making the installation process easy and affordable hence enhancing efficient and cost-effective power infrastructure.
They are also suitable for temporary power connection arrangements for instance in construction sites or mobile substations because of their simplicity in connection and ease of installation.
Most of these support insulators are found in low to medium-voltage transmission lines where high insulation characteristics are not so much required offering optimum between efficiency and cost.
