DISTRIBUSION SILICONE INSULATORS LINE POST

Silicone rubber line post insulator have very good ultimate solution,due to its

hydrophobicity,this material inherently resists water filming thereby limiting

leakage currents.silicone rubber insulators reduce leakage currents ,even when

contaminated and require less frequent washing.the savings in such maintenance

costs are added benefits of using silicone rubber insulator.

1.Performance benefit of distribution line post insulator         

1.Improves Reliability (by minimizing interruptions and outages due to vandalism,

Pole fires,and flashovers in all types of enviroments)

2.Eliminates or Reduces Maintenance (such as washing and trouble calls) and is 

compatible with existing plant

3.Improve Power Quality(less RI and TVI)

4.Energy Efficiency (lower losses due to lower leakage currents)

5.Safety (light weight for handling and installation)

6.Service Life( consistent performance over its service life)

7.Life Cycle Cost(Savings over ceramic insulators)

2. Application                                                 

Distribution silicone line post insulators are used on overhead distribution lines 

operating at and below 69KV.These insulators are commonly installed on metal,

concrete or wooden structures to horizontally or vertically support the line 

conductor.also these insulators can be used to support high voltage conductor 

jumpers or leads.

3.Material                                                  

1.Core rod

The core rod of the insulator is made of a high quality,epoxy resin,Fiberglass rod

that has been specially formulated for electrical and mechanical applications.

2.Housing

The housing (includes sheath and sheds)of the insulator is one piece,high temperature

vulcanized ,injection molded silicone rubber that is chemically bonded to the core

rod.This ensures that the interface between the rubber and rod is impenetrable

against moisture ingress.TID Tech uses its own proprietary silicone rubber formula

in the manufacture of its insulators.the formulations has silicone rubber as the

base polymer material with additives to enhance its performance in wet contaminated

environments.

3.Line End Fitting

The line end fitting of Line Post Insulator are available in four different

configurations: Horizontal or Vertical Clamp-Top,Tie-Top,or K-clamp.

End fittings on line Post Insulators are made of corrosion resistant aluminum alloy

or galvanized iron castings.

Section Length Adjustment

Clamp-Top

The conventional horizontal and vertical trunnion accommodates a standard Line post 

insulator,bolted conductor clamp.One the horizontal design the line end fitting has 

and additional eye for the attachment of other devices during installation or 

maintenance activities.

Tie-Top 

The tie-top is designed for tying a conductor to the neck of the insulator.it is a 

available in two standard neck sizes: C or F-neck. 

K-clamp

Some advantages of the K-Clamp include:

1.Excellent corrosion resistant aluminum casting

2.A long,smooth contoured conductor clamping zone

3.The clamp accommodates a full range of conductor size

4.A single captive live-line operable bolt

5.All parts are captive

6.Its overall length permits standard cover up hoods to effectively cover all 

insulator sheds.

7.The design can be installed in either a horizontal or vertical configuration.

8.Inventory reduction is accomplished because one insulator is used for both 

configurations and a separate clamp is not required.

9.The price of the new insulator is cost comparative with the purchase of a 

standard turnnion post insulator and a separate clamp

10.Substantial labour cost savings in stringing ,sagging and conductor clamping

11.Other savings related to shipping,stocking and maintenance.

Base end Fitting

The standard base for line post insulator is a round flat iron bas with a threaded 

hole that accommodates a standard insulator stud or bolt.for other special bases
