APPLICATION
PYUNGIL polymeric feeder wire support insulators for railway (NSP-50) employ silicone rubber for main insulation material, an FRP rod with high mechanical strength and aluminum alloy in accordance with ASTM B26M. Compared to the existing railway insulators, the insulators are light- weighted and accordingly easy to handle, though they offer reliable quality mechanically and electrically. Moreover ultimate compression and tensile strengths of NSP-50 ensures dependable quality and security.
NSP-50 is used to hold feeder wire reversely at electrical railway system for 25kV. The bottom fitting has 4 holes to be fixed onto ceiling and the other clamp fitting is designed to securely hold the feeder wire. According to the customer's requirement on the creepage distance, the number of weather sheds is changeable.
PYUNGIL insulators are designed and manufactured under the rigid quality compliance of the ISO 9001 quality assurance program. |
