Industry Pain Points and Company Solutions
In power transmission and distribution lines, guy insulators play a critical role in isolating guy wires from towers, preventing current leakage, and ensuring personal safety. Traditional single-material guy insulators often face the following challenges: porcelain insulators, though aging-resistant, are brittle and fragile, resulting in high loss rates during transportation and installation; glass insulators require timely replacement after self-explosion, increasing maintenance costs; composite insulators vary in weather resistance, and inferior products are prone to aging and cracking. Hejian Haokang Electric Co., Ltd. deeply understands the practical pain points of line operation and maintenance units. Relying on years of experience in insulator production, we have integrated guy insulator series in three materials—porcelain, glass, and composite—to provide customers with tailored combination solutions based on local conditions. From raw material screening to kiln firing, from glass tempering to core rod injection, our factory implements batch traceability and mechanical tensile sampling inspection throughout the entire process, ensuring that every insulator can withstand long-term environmental and mechanical stress in actual service.
Product Working Mechanism and Detailed Features
The guy insulator is connected in series in the guy wire. Its metal fittings and insulating parts are integrated by cementing or mechanical locking, allowing it to withstand the tensile load transmitted by the guy wire while blocking current. Depending on different line voltage levels, our factory offers the following three mainstream material series:
- Porcelain Guy Insulator: Made of high-strength alumina porcelain, fired at temperatures above 1250°C, the porcelain body is dense and free of pores, resistant to contamination and UV aging, suitable for heavily polluted areas or high-temperature, high-humidity environments. Typical model JH10-90, mechanical tensile load ≥90kN, creepage distance 450mm.
- Tempered Glass Guy Insulator: Uses tempered glass components with surface compressive stress >120MPa. After self-explosion, the fragments are small diamond-shaped pieces, making it easy for patrol personnel to visually identify hidden damage; it also features zero-value self-explosion, eliminating insulation failure, and is suitable for transmission lines requiring rapid fault location.
- Composite Guy Insulator: The core rod is made of epoxy glass-fiber reinforced material, and the shed is made of high-temperature vulcanized silicone rubber. The overall weight is only 1/3 of that of a ceramic product of the same class, and it has excellent hydrophobicity, effectively suppressing pollution flashover. Our composite series has passed a 1080h salt-spray aging test, and the tracking resistance performance reaches TMA 4.5 level.
