Polymer Suspension Insulator

The Polymer Suspension Insulator XP-70-Y is an ANSI standard polymer suspension unit designed for lightweight transmission applications. It belongs to the 70 kN class. The structure height is 146 mm, and the disc diameter is 254 mm. The mechanical failing load reaches 70 kN. The product complies with ANSI C29.2 standards. The "Y" in the model indicates a long shank design. The creepage distance is 292 mm.

The polymer housing provides important advantages in transportation and installation. The lightweight structure reduces handling difficulty and helps lower installation costs. The silicone rubber surface has natural hydrophobic properties. Water drops remain separated instead of forming a continuous conductive film. This improves pollution resistance and helps maintain stable insulation performance in wet environments. Suspension units are normally installed in strings, so a single unit does not have a fixed rated voltage. This Polymer Suspension Insulator is widely used on high voltage transmission and distribution lines in North American power networks.

We use automated injection molding equipment for polymer production. The process keeps product dimensions stable and improves batch consistency. Our engineers pay special attention to the bonding between the core rod and silicone rubber housing because this area affects long-term reliability.

We perform interface sealing tests, water diffusion tests, and steep front impulse tests according to product requirements. Each unit also undergoes mechanical tensile testing to verify the 70 kN load performance. Our quality team checks every piece carefully for surface defects, including bubbles, uneven rubber coverage, or shed damage.

We support customized appearance options. Customers can choose different silicone rubber colors, including grey and red. Our technical team can also review drawings and application conditions to help select suitable specifications. The product has been supplied for overseas power projects, including applications in North America, where customers value its lightweight structure and stable outdoor performance.

The normal delivery time is 30 to 40 days. We accept trial orders for project testing and evaluation. Sample support is available with freight collected. We accept T/T and L/C payment methods and support FOB and CIF trade terms.

We use export cartons or wooden cases with internal protection materials for shipment. Each unit is fixed properly to reduce movement during transportation. The warranty period is 12 months after shipment. If quality problems occur, our technical team responds within 24 hours and provides suitable solutions.

This Polymer Suspension Insulator offers a practical combination of lightweight construction, pollution resistance, and reliable mechanical strength for ANSI-based transmission line applications.

All products support custom dimensions, voltage ratings, OEM/ODM services, and manufacturing based on drawings.
