Available in 25k, 30k, 50k and 80k tensile strengths. Modular suspension insulators are custom products typically used for applications of 230kv and above. Which can be used from 11kv to 1100kv transmisson line and distribution line.
China 138kV Composite Suspension Insulator Manufacturers
The suspension insulator separates the line conductors and supports them electrically.
Due to the limitations for higher voltage in pin type insulators, suspension insulator types are employed in towers.
Composite suspension insulators is a main type composite insulatorswhich also named composite long rod insulator, composite tension insulator, polymer suspension insulator, silicone rubber suspension insulator. Suspension insulators for transmission & distribution. Cap and pin type & interlink type are the types of suspension insulator, and it has several advantages. Porcelain suspension type insulators supports mechanical charges from 10,000lb and up to 25,000lb.
Consist of fiberglass rod core, hdg end fittings, silicone rubber sheds.
These can be simply noted by the collector when describing the insulator. Distribution (69kv) indoor (35kv) insulator accessories; It consists the number of porcelain insulator units connected with each other by metal links to form a flexible string. The suspension insulator separates the line conductors and carries them electrically.
Manufactured and designed complying with ansi standard.
Description for composite suspension insulator: The suspension insulator consists mainly of two parts one is the cross arm and the other is the insulator which we also know as the disc insulator. The pin insulator supports the wire at the top or at the one side as shown in fig. Ordinary insulators are suitable for general use.
Transmission (69kv+) line construction hardware.
Mps offers a wide variety of standard and custom suspension. An insulator’s two main functions are mechanical and electrical, and failure of either function could lead to. Manufactured in state of the art iso9001 certified facilities. Suspension insulators often use a standard insulating shell, and can be fitted with a myriad of connection types based on the needs and preferences of an end user.
Wet process porcelain manufacturing system.
Routine testing as per ansi c29.2 includes thermal shock test, tension proof test and flashover test. The modular design offers the ability for custom applications to adapt to any end user's unique environment. For a suspension insulator with. Insulators are classified into two types according to their environment and area.
Suspension type insulator includes one or more insulator parts connected together in series to form a string, and they are hanged to the cross arm of the tower or supporting structure and carry a power conductor at its lowest extremity.
Utilities rely on us for products that will stand the test of time with as little maintenance as possible over the years. With a proven track record of over 80 years of manufacturing, over 30 million units in service, and a reliability record that far exceeds that of similar glass insulators or other porcelain manufacturers, the suspension insulator from lapp insulators provides today's engineers something that is missing from many other manufacturers and products, peace of mind. Molded suspension insulators are standard products ideal for tension applications from 69kv to 161kv. Our suspension insulators combine the high tensile strength of fiber reinforced plastic (frp) with high voltage shed profile, to produce a rugged, lightweight suspension insulator for overhead line applications.
Select “p” or “s” for post or suspension, respectively, and fill in your selection in the box designated for “a.” in this example, we selected a suspension insulator.
With the number of metalink links. A suspension insulator, which is also known as a strain insulator, is a type of insulator designed to protect the overhead power line. Defines the leakage distance design. Suspension insulator or disc or string insulators.
It is supported with a steel bolt or pin which is fixed on the cross arm.
It consists of the number of porcelain insulation units connected by metal links to form a flexible cord. Designed in compliance to ansi c29.2 standard (please contact us to certify compliance to other standards). Suspension insulators or suspension strings are developed by attaching a number of closed insulators in series using metallic links. Suspension insulators are what originally made high voltage transmission possible, and consist of individual units designed to support a particular voltage.
The main types of insulators used for overhead lines are.
Advantages of the suspension isolator the suspension isolator has the following advantages. Suspension clevis tongue 69 kv. The glass fiber core provides high mechanical strength with tensile values of greater than 70 kn/15,000 lbs.
