It is widely used in medium and high voltages of transmission lines. For analyzing the double 500kv suspension insulator string flashover causes, high voltage power lines may choose double suspension insulator string. String efficiency of suspension insulator :
Double suspension insulator chain (set) Plamen
Double suspension set, double tension set for twin acsr.
Each insulator of a suspension string is called disc insulator because of their disc like shape.
230kv double suspension i type insulator string over head transmission line joint fittings. The specifications and technical data of these suspension or tension sets are different as follows. The suspension insulator can be classified as single suspension insulator string and double suspension insulator string. For double suspension string insulator assemblies, the pulleys shall be connected to the yoke plate of the hardware.
The conductor is suspended at bot.
View photo of line fitting, cable joint and kiting, double suspension circuit.contact china suppliers for more products and price. 230kv double suspension i type insulator string over head transmission line joint fittings picture from ningbo hyuan power industry co., ltd. 1.2 before hoisting, all insulators are cleaned in a manner that will not. Suspension composite insulator has features of light weight, small.
1.1 single / double suspension insulator strings are used on suspension towers and single / double tension insulator strings are used on angle and dead end towers.
In suspension insulator numbers of insulators are connected in series to form a string and the line conductor is carried by the bottom most insulator. It consists the number of porcelain insulator units connected with each other by metal links to form a flexible string. The conductor is connected at the bottom of the string. Where paying out / stringing shall be done through tension tower, pulleys are normally connected directly to the.
They typically consist of a series of porcelain or glass insulator bells (figure 2) or a polymer rod (figure 1).
Double suspension set for twin acsrand double tension set for twin acsrare opgw fittings. Double tension insulator string features: Suspension type insulator consists of number of porcelain discs connected in series by metal links in the form of a string. The single suspension insulator string can be used together with the other type of insulators on some certain conditions.
Precision engineered dimensional accuracy quality tested high insulation.
Orient power is a successful insulator manufacturer, supplier and. Suspension insulators or string insulators are very widely used in electrical overhead transmission system. Their attachment to the structure via a pinned connection allows the insulator to. Possibilities, our suspension composite insulator can be used for.
Double suspension set for twin acsr 435/55 sq.
Why do take place this accident??insulator creepage distance unreasonable choice, effective. Generally, in overhead transmission lines, we use a number of porcelain discs as an insulator that is arranged in string. The suspension insulator is shown below. This type of insulator is also called a suspension insulator, and the number of insulator discs connected depends upon operating voltage.
This is indicated in the tower schedule.
Badly polluted areas, high mechanical tension load, long span and. Each suspension disc is designed for normal voltage rating 11kv. The suspension insulator string is used in the vertical direction. Resistant and strong explosion protection.
Just the same as the string insulator, a suspension insulator is a flexible insulator string that consists of some porcelain or glass disc insulators connected with each other by metal connections.
500kv suspension insulator string is easy to take place the flashover trip accident, especially the double suspension insulator strings. Us $150 / piece |. The suspension insulator separates the line conductors and supports them electrically.
