  1. TRANSPORTAION & INSTALLATION &HANDLING
 
1.1  INSTRUCTION FOR TRANSPORTATION & HANDLING
  1. Recommend the use of single insulator cylinder packaging style, have prevent rodent and deformation preventing measures on packaging, warehousing and properly stored.
  2. Transport and handling of insulators must be carried out in the packing case, when the insulator length exceeds the transport vehicle body, should also take to prevent the insulator deformation measures.
  3. Handling the removal of the outer packaging of the 330KV and above grade insulator, insulator should be smooth handling, prevent excessive deflection


1.2  INSTRUCTION FOR STORAGE
a.The cardboard tubing stacked in a warehouse should be less than 8 layers
b.The goods must be stored in a clean,ventilated and dry warehouse, and avoid damage by termites and rats.
c.Do not store the insulators outside without any covering; Fireproof and avoid to be exposed to the sun.
1.3  INSTRUCTION FOR INSTALLATION
  1. The socket and ball of the composite insulator shall be connected to the hardware fittings. The coupling procedures are as follows:
    1. To pull the Split-pin from the Locking Position to the Coupling Position with suitable tools.
    2. To insert the ball into the socket to make the ball and socket couple.
    3. To Push the Split-pin to the Locking Position with suitable tools.
                             
        Split-pin in Locking Position                   Split-pin in Coupling Position  
 
  1. During the installation, make sure that the weather sheds are not damaged or hurt and the composite insulators are not subjected to bending and twist loads.
  2. Don’t scramble along the insulator string during installation or maintenance.
NOTE: In the installation process, to avoid excessive bending or torsion stress on the mandrel. At the same time in the hanging line, do not turn the insulator has a fixed or add load
 
  1. DETECT and MAINTENANCE
 
2.1  Visual measurement method for the online detecting
 
Using the eyes to observe the operational aspect of the composite insulators, our professional team can make it sure whether they are operating well or not. For the composite insulators operating nearby, like station or insulation components, we can observe by naked eye. For the composite insulators operating on the overhead line or far away, we need to use the binoculars.
(For insulator defects like: apparent defect, serious flashover, serious aging, end-fitting breaking off, core rod breaking off)
 
 
2.2  Ultraviolet image method for the online detecting
 
Monitoring the operational aspect of the composite insulators by Uv imager,our professional team can make it sure whether they are operating well or not.
(For insulator defects relate to electrod bnormal glow like:
aging,cracking)
 
 
 
2.3 Infrared image method for the online detecting
 
Monitoring the operational aspect of the composite insulators by ultrasonoscope,our professional team can make it sure whether they are operating well or not.
(For insulator defects relate to unusual heating like:interface breakdown,cracking)
 
2.4  Ultrasonic testing method for the online detecting
 
Monitoring the operational aspect of the composite insulators by ultrasonoscope,our professionalteam can team make it sure whether they are operating well or not.
(For insulator defects relate to partial discharge like: cracking of the core rod,local damage)
 
 
2.5  Troubleshooting for the composite insulators operating online
For the transmission line, when the line tripping happen, our professional team can troubleshoot it. The method for our professional team to solve the problem is showed below:
 
What’s more, to make it sure that the transmission line is working well, we need to the check the operational aspect of the composite insulators. For this, we may do the random check for the composite insulators operating on line regularly, or we can also disassembly the composite insulators of the random power transmission tower and test them in our laboratory.
