从India供应商批量进口45 Kn Disc Insulators

These are 45 kN disc insulators engineered for overhead power transmission lines, conforming to IS 731, IS 3188/1980 and IS 2486 standards. Each disc features an outer diameter of 255 mm, a vertical distance between centres of 145 mm, and a creepage distance of 290 mm, with dimensional tolerances as per IS 3188. The units weigh approximately 4.5 kg each and are packed in wooden crates, with four insulators per crate for a gross weight of 22 kg.

The insulators are manufactured from electrical-grade porcelain or composite materials, typical for this application, and are designed to withstand mechanical loads up to 45 kN. Typical industry standards for such insulators include a dry power frequency withstand voltage of 70 kV at 50 Hz and a wet power frequency withstand voltage of 40 kV at 50 Hz. The dry impulse withstand voltage for a single unit is rated at 75 kV for both positive and negative waves (1.2/50 µs).

These components are primarily used in medium and high-voltage transmission networks to isolate conductors from support structures, preventing current leakage. Buyers include utility companies, infrastructure contractors and electrical equipment distributors sourcing for grid expansion or maintenance projects. Typical trade terms involve bulk shipments with wooden crate packaging, and buyers should confirm incoterms, lead times and inspection requirements directly with the supplier.

Balaji Electrical Insulators Pvt Ltd is based in Works Village, Balol, on the Mehsana-Balol Highway in North Gujarat, India. The company manufactures disc insulators and other electrical components, with a focus on products that meet Indian Standards (IS) for dimensional and performance specifications. The supplier’s listed address confirms its operational presence in the Gujarat industrial belt, a hub for electrical equipment manufacturing.

The supplier’s profile does not disclose additional details such as year of establishment, production capacity, or certifications beyond adherence to IS standards. Buyers should verify manufacturing capabilities, quality control processes and compliance documentation directly with the company. The response rate and trust tier signals are not available, so prospective importers are advised to request samples and technical data sheets before placing orders.
