The KSPC 120-3\/0.6 Polymer Tension Rod Insulator<\/strong> is designed for railway overhead contact line systems operating at 3 kV DC<\/strong>.<\/p>\n

It is used to support and electrically isolate contact network conductors, suspension components, and fastening elements from grounded structures while maintaining high mechanical strength and long-term reliability.<\/p>\n

Manufactured with a fiberglass reinforced core rod<\/strong> and a silicone rubber housing<\/strong>, the insulator provides excellent resistance to pollution, moisture, UV radiation, and mechanical loading, making it suitable for harsh railway environments.<\/p>\n

Key Features<\/h2>\n
    \n
  • High mechanical tensile strength up to 120 kN<\/strong><\/li>\n
  • Silicone rubber housing with excellent hydrophobic performance<\/li>\n
  • Superior resistance to contamination and tracking<\/li>\n
  • Lightweight compared to porcelain alternatives<\/li>\n
  • Suitable for severe pollution areas (Class III\u2013VII)<\/li>\n
  • UV-resistant and weather-resistant construction<\/li>\n
  • Maintenance-free operation<\/li>\n
  • Designed for railway overhead catenary and contact line systems<\/li>\n
  • Long service life in outdoor environments<\/li>\n<\/ul>\n
