What is the Rigidity Suspension Midpoint Anchor Long Rod Insulator?

The Rigidity Suspension Midpoint Anchor Long Rod Insulator is a type of composite insulator for high-tension transmission lines to meet the insulation and mechanical stresses. Of all these insulators, this is most commonly implemented at the midpoint attachment stations where suspension and overall rigidity are paramount. It incorporates the features of suspension and anchor insulators and is well suited for the line sections that require an extra degree of stiffness and means for attachment to the support structure. It is fabricated with state-of-the-art composite materials; Its key component is the fiber-reinforced resin rod where the use of modern composite material provides high mechanical properties, resistance to environmental degradation, and high resistance to electrical discharge. It conforms to a silicone rubber housing and thus has a very low surface energy, which means it is very hard for contaminants such as dust or water to stick on its surface thus significantly reducing the chances of flashover occurring.

Purpose

This type of long rod insulator was developed to solve certain issues related to high-voltage transmission lines such as insulator point which requires more stability and mechanical force. This insulator has the dual role of covering the electrical insulation requirement and bearing the mechanical load of the conductors, especially for those portions where either the direction of the line changes or midspans or where the conductor demands extra support to remain in position. This type of insulator was designed to eliminate weaknesses that are commonly related to both suspension and anchor types of insulators. Combining the dynamics of suspension and anchoring facilitates the stability of the transmission line while at the same time minimizing line swing, conductor gallop, or any other disruption that is mechanical thereby balancing the general performance and safety of the power transmission line. The design also improves the insulator’s resistance to environmental loads like wind and ice as well as seismic loads improving the reliability as well as durability of the transmission line structures.

Benefits

1. Enhanced Mechanical Stability:

This composite long rod insulator offers some form of support to conductors, particularly at the midpoint and other areas such as transitions where there is a likelihood of the conductor swinging or causing mechanical havoc on the system due to instability.

2. High Electrical Insulation:

They are manufactured from advanced composite materials with appropriate electrical characteristics to provide good insulation in high-voltage usage.

3. Resistance to Environmental Stress:

Provides enhanced protection against severe weather factors such as wind, ice, and pollution that necessitate little or no maintenance and therefore have great durability.

4. Reduced Maintenance Costs:

The materials used are long-lasting, and the equipment constructed strongly means that it will require infrequent inspections and repair which in the long run translates to lesser service cost of the insulator.

5. Improved Line Reliability:

This integrates two key actions, suspension, and anchoring that improve the credibility and performance of the transmission line to ensure an unintermissible and consistent power supply.

6. Lightweight and Easy Installation:

Using lightweight composites makes the insulator more manageable, thus decreasing handling, installation time, and costs.

Application

1. Midpoint Anchoring:

Found in the middle of the transmission to offer provision for conductor stability and minimize the conductor sag.

2. Line Direction Changes:

Used at locations that result in changes in the direction of the transmission line, to control mechanical forces as well as ensure proper placement of conductors.

3. High-Voltage Transmission Lines:

Typically installed at transmission voltage power systems for conductor suspension and electrical insulation of conductors from the grounded structures to minimize chances of electrical faults and to ensure safe electrical distances.

4. Transition Towers:

These insulators are evident on transition towers which are points where the mechanical load is either suspended or pulled in the line of tension by towers.

5. Harsh Environmental Conditions:

It is suitable for applications in regions with adverse conditions for example, strong winds, heavy ice, and corrosive atmospheres based on its adverse environmental stress resistance.

6. Mountainous or Difficult Terrain:

This anchor insulator is used in difficult topographical conditions to enhance the anchoring capacity for the management of the line tension about different geographical heights and terrains.
