Description:

1, 25kV composite railway insulators are widely used in electrified railways

2, Dead end fittings are up to the requirements from the clients, usually we use ball, socket, tongue, clevis for tension insulators with forged steel or cast steel.

The dimensions and coupling size can be exactly according to the specification requirements from the utilities.

3, The silicon rubber color of the insulators are also up to the requirements from the clients and all the silicon rubber materials past 5000 hours aging test silicon content test and hydrophobicity test.

4, ECR core rods are used in all the insulators, so we can guarantee a very good mechanical strength and anti-acid pollution performance for the insulators.

5, All our insulators were type tested and design tested in accordance with IEC61109, maximum RIV is 100µV when tested at 1MHz and10% over nominal line ground voltage for indicated system voltage.

Applications:

1, Used in electrified railways

Competitive Advantage:

The advantages of polymer/composite insulators over ceramic/porcelain insulators
General comparison
Factor	Ceramic/porcelain insulators	Polymer/composite insulators
Weight	Heavy weight- For example 400kV - about 140kgs	90% lighter than them but with same mechanical strength 400kV -- Around 15kgs
Fragility	Highly fragility to shock and vibration	No fragility to shock and vibration
Packing and transportation	Risky and very costly	Easy and economical
Installation	Risky expensive and more labor required	Very easy and economical
Handling	Difficult	Easy
Maintenance cost	Very expensive	Low
Vandalism	More susceptible	Highly resistant
Breakages and secondary damage	Highly fragile- 10-15% breakages are reported during transportation storage and installation< You May Like Ductile Iron Pipe Fittings Ductile Iron Pipes China supplier sand casting epoxy ductile iron pipes china pressure pipelines ductile iron pipes ISO 9001 Machined GGG50 Ductile Iron Sand Casting Pipe Manufacturer Best Price Custom Sand Casting Ductile / Grey Iron Pipe Custom Sand Casting Ductile Iron Sewage Pipes TS16949 Manufacturer Fully Automatic Molding Line Sand Casting Ductile Cast Iron Rod Kinds Of Cast Pipes Price List Ductile Iron Pipe Stair Basket K9 Cast Steel Wrought Components Ductile Iron Pipe Popular Searches ductile pipe Ductile Iron Pipe ductile iron pipe class k9 ductile iron pipes coates cement cement line pipe ductile pipes ductil pipes ductile iron pipe in dci pipe prices for ductile iron pipes gsxr 1000 k7 wras certified ductile iron manufacturer iron ductile pipes wholesale ductile iron pipe ductile iron pipe factory Find Similar Products By Category Minerals & Metallurgy > Iron > Iron Pipes You May Like Fittings Decoration Wrought Fence Panel And Gate Ductile Iron Pipe Wire Bird Cage Spear Fence Decorative Wrought Onion Basket Ductile Iron Pipe Models Cheap Fence Decorative Wrought Panel Ductile Iron Pipe Balusters Components Wrought Garden Ornamental Ductile Iron Pipe No-hub Cast Balusters Wrought Gate Ornament Ductile Iron Pipe Wrought Scroll Sml Cast Fittings Weight Per Meter Ductile Iron Pipe Class K7 Cast Gate Accessories Ductile Iron Pipe Valves Craft Wrought Flowers And Leaves Ductile Iron Pipe Fence 150mm Stair Decorative Panels Ductile Iron Pipe Flower Leaf Design Wrought Villa Gate Designs Ductile Iron Pipe K7 Single Wrought Gate Cast And Fittings Ductile Iron Pipe Spearhead 600mm Cast Drain Fittings Ductile Iron Pipe Price Cast Pipes Wrought Fence Ornaments Ductile Iron Pipe Fencing Fence Wrought Railing Parts Ductile Iron Pipe Cast Rosettes House Gate Ornamental Wrought Fence Components Ductile Iron Pipe View More Home\|Products\|PC Sites \|Site Map Hot Words \|September,2024 京ICP备2023035610号-3 Chat Now Contact Now
