The cap and pin type toughened glass insulator is one of the main products.In 1958,the first piece of toughened glass insulator has been created in Nanjing Ceramic Factory. Over more than 50 years there are billions pieces toughened glass insulators brand LD had been put into operation on 30-1000kv transmission lines, andmore than 2.5 million pieces abroad.At present, 20 million pieces of high tonnage glass insulator which produced by imported production line have been used at home and abroad on 500500~1000kV lines. We achievedbreakthrough in UHV transmission lines and filled the blank of this product for HVDC project in china. 10 + 800kV lines, 6 1000kV lines share 2 million 600 thousand pieces of glass which become the best in the industry and the world.
Composite insulator is made up of ,with its advantages such as small in size、light weight、convenient to maintain and fouling. We can supply a complete products such as :10-1000kV(40-600kN) AC Suspension composite insulator; ±1100kV（120kN~1000kN） DC composite insulator; 330 kV wind-resistance composite insulator ; Ground composite insulator ; Railway rod type composite insulator.
