Polymer long rod insulators are one of polymer insulators, also called composite suspension insulator used any voltage level transmission and distribution power lines, such as 10kv and 500kv overhead lines.
The features of polymer long rod insulators
◆ Materials: silicone rubber, steel
◆ Manufacturing process: molding or whole injection
◆ Structure: FRP core rod, insulation housing and metal end fittings
◆ Application: transmission and distribution overhead lines
The shed profile option of polymer long rod insulators
◆ Same sheds
◆ Big and small weathersheds
Polymer long rod insulators test
◆ Tensile load test – time test
◆ Power arc test
◆ Tracking wheel aging test
◆ Long duration aging test
Polymer long rod insulators are designed in mechanical strength including 70kn, 80kn, 90kn, 100kn, 120kn, 160kn, 210kn, 300kn, 530kn, 450kn, etc.
