Discharge Rod

Product Specification

Discharge Rod

  1. MAIN OPERATING POLE : ‘F’ Class Insulated tube made of Fibre Glass Epoxy Bonded having insulation properties suitable for 400kV and above system coupling type or Telescopic Type. Recommended length of Pole is 6.5M for 40kV Sub Stations and 5.0M for 220kV Sub-stations or 40kV Transmission Lines. Poles are tested as per IEC 1230 for mechanical strength and IEC 1235 for Dielectric strength.
  2. MAIN FIXING HOLDER : It shall be spring loaded to attach/detach the line end clamp by rotating clockwise/anti-clockwise direction. It is made of aluminium alloy in ‘Die-cast’ process. It is bolted in the main operation pole.
  3. LINE-END CLAMP FOR ACER : It is made of aluminium alloy, in ‘Die-cast’ process. It is a spring loaded jaw type clamp with conical stainless steel screw pin for clamping any type of conductor from 20mm to 40mm dia. It has arrangement for fixing the earthing lead in outer insulation as well as inner conductor. Tested as per IEC 1230.
  4. LINE-END CLAMP FOR 4″IPS : It is ‘C’ hook-on type Duckbill clamp made of aluminium alloy in Die-cast process with stainless steel conical pin fitted with contact plate of aluminium alloy for clamping round IPS Bus bar up to 112mm diameter. It has arrangement for fixing the earthing in outer insulation as well as inner conductor. Tested as per IEC-1230.
  5. EARTH-END CLAMP : It is made of aluminium alloy, in ‘Die-cast’ process. It has stainless steel screw pin rounded at bottom to fix on tower angle up to 25mm thickness. It has arrangement for fixing the earthing lead in outer insulation as well as inner conductor. Tested as per IEC 1230.
  6. EARTHING LEAD : Flexible PVC insulated braided earth lead of aluminium or copper conductor of required length. Teflon/polyester film taped cable is also supplied on request at additional cost. It is tested for short circuit current of 8 KA for 1 second as per IEC-1230.
  7. CARRY BAG : It shall be made of canvas for safe storage & transportation of the rod.
