Import Composite Insulator(10-330kv) — Buy in Bulk from Supplier in China

Composite insulators for 10 to 330 kV systems are engineered for overhead transmission and distribution lines, with Zhejiang Hitt Electrical Co., Ltd. offering pin-type (FPQ), suspension (FXB), and post (FZS) variants. These units replace traditional porcelain or glass insulators with a lightweight silicone rubber housing and fibre-reinforced polymer core, reducing tower loads and simplifying installation. The supplier’s range covers the full medium- to high-voltage spectrum, with each model matched to specific mechanical and electrical class requirements.

The housing is formulated from HTV silicone rubber, chosen for its hydrophobic properties and resistance to tracking and erosion under polluted conditions, a critical advantage in coastal or industrial regions. The core is typically pultruded E-glass fibre in an epoxy matrix, providing tensile strengths that exceed 1000 MPa, a standard benchmark for composite insulators in this class. End fittings are hot-dip galvanised steel or aluminium, crimped to the core to ensure long-term mechanical integrity, with typical corrosion protection exceeding 30 years in temperate climates.

Utility providers and EPC contractors source these insulators for new line builds and refurbishments where weight savings and pollution performance are priorities. Common applications include river crossings, urban corridors, and polluted areas where ceramic strings would require frequent cleaning. Buyers should confirm the specific mechanical load class, creepage distance, and pollution severity rating for their project, as these parameters drive model selection and string configuration.

Zhejiang Hitt Electrical Co., Ltd. operates from Chongshi Industrial Zone in Baixiang, Zhejiang Province, China, with a focus on electrical transmission and distribution components. The company’s profile indicates it is an imported-tier supplier, positioned to serve international buyers, though its current response rate on the platform is not available, suggesting direct contact is necessary for inquiries.

The supplier specialises in composite insulators and related hardware for overhead lines, with no additional product categories or certifications explicitly stated in the provided data. Buyers should verify factory capabilities, quality control processes, and any third-party testing certificates directly with Zhejiang Hitt Electrical Co., Ltd., as these details are not listed in the public profile.
