This 110 - 220kV insulated cross-arm is specifically designed for high-voltage grid operations. Its production demands meticulous planning, advanced manufacturing techniques, and stringent quality assurance procedures, all of which signify the producer's expertise. As a type of post insulator, it adheres to relevant IEC standards for post insulators. However, it has distinct characteristics. Unlike typical vertically-installed post insulators, this insulated cross-arm is installed horizontally or at an inclined angle. Consequently, it demands enhanced bending strength and places emphasis on lightweight construction.
During its service, it not only isolates the conductors electrically but also endures diverse mechanical stresses, including those from strong winds, heavy ice loads, and the conductor's own weight. The customized end fittings ensure a secure and adaptable connection with the conductors.
It showcases outstanding electrical insulation capabilities and robust mechanical endurance, can withstand a wide range of environmental conditions, and is highly valuable in high-voltage power transmission, especially in regions with challenging environmental circumstances.
Standards:
IEC 61952-1-2019; ANSI C29.18
Specifications:
Application:
It is predominantly utilized on pylons or towers in the power grid, especially in high-voltage transmission lines. Its core function is to furnish stable electrical insulation and mechanical support to the conductors, which is of utmost importance for the dependable operation of the power transmission network and the continuous supply of electricity to consumers.
Features:
● Exceptional Dependability:
Meeting the specific demands of the high-voltage grid, it can operate reliably for an extended period, reducing the need for frequent maintenance and ensuring the uninterrupted flow of power.
● Tailored Design for High-Voltage Insulation and Mechanical Demands:
Its structure and material selection are carefully optimized, with a focus on both withstanding high voltages and coping with the unique mechanical load patterns it experiences. It takes into account the difficulties of maintaining insulation and withstanding non-vertical forces in a power grid.
● Superior Anti-Environmental Resistance:
Considering the potential environmental adversities in different areas, it has effective countermeasures to mitigate these impacts and guarantee the normal functioning of the power transmission network.
● Broad Adaptability to Varied Conditions:
With remarkable performance in handling various external forces and environmental fluctuations, it can effectively execute its insulation and support roles for the conductors under a wide array of operating conditions.
