Composite Suspension Insulator

The Composite Suspension Insulator XP-70-A is a ball and socket suspension type designed for 70 kN mechanical load applications. The structure height is 146 mm, and the disc diameter is 255 mm. The mechanical failing load is 70 kN. This product complies with IEC 60305 and GB/T 7253 standards. The "A" indicates a ball and socket connection. The creepage distance is 295 mm. The ball and socket interface size is φ16. This connection design provides flexible installation and allows multi-directional movement. Suspension insulators are normally installed in strings, and a single unit does not have a fixed rated voltage. We use electrical porcelain material for the product body. The ceramic structure is dense and provides good weather resistance. This product is used in suspension strings and tension strings for high voltage transmission lines.

We pay close attention to quality control during suspension insulator production. Suspension products require high mechanical load performance. Our testing equipment performs individual tensile load tests on products. We have 21 technical staff who focus on mechanical and electrical performance coordination. We inspect the ball and socket joint dimensions of each unit to ensure compatibility with standard hardware. Before shipment, we conduct power frequency breakdown tests and porosity tests on each batch. We provide assembly recommendations, including the recommended number of units and suitable hardware configurations. The product has been tested at the National Insulator Arrester Quality Supervision and Testing Center. We also provide zinc sleeve anti-corrosion treatment options. This helps improve the service performance of the Composite Suspension Insulator in outdoor transmission environments.

Delivery takes 25 to 35 days. We accept small trial orders and provide free samples with freight collect. We support FOB, CIF, and DDP trade terms. We pack products on wooden pallets with cartons, and each piece is separated with foam protection. We provide production progress photos and video updates during manufacturing. The warranty period is 12 months. For transit damage, we replace the damaged quantity or provide compensation according to the actual situation. This Composite Suspension Insulator is a reliable component for high voltage transmission line strings.

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