we offer high quality Polyethylene Pin type insulators .
Comparing with traditional material insulators ,HDPE insulators have good advantanges :
1 Very light unit weight , it is easy for transporation , line assembly operations , it can low down much labours during distribution lines construction .
2 Excellent aging -prooft performance ,
3 The material is easy for mataintence , the material is not broken , when attacked by bullet , birds , or other violence .
4 Excellent self-cleaning character .
5 The HDPE insulators can be auto-production from prodiction lines , so production period will be very short , that means we can make very fast delivery after PO .
