JY-01
This insulation bracket serves as a dedicated mounting accessory for surge arresters and disconnectors in power distribution systems. It provides insulation support and fixed positioning for surge arrester installation, enabling secure mounting on power cross-arms. After the lightning arrester is assembled, compatible disconnectors can be installed below the insulating bracket to complete the full set of equipment. Designed for commercial procurement in power transmission and distribution projects, model JY-01 aligns with standard power system mounting dimensions. It is suitable for industrial clients engaged in overhead line construction, retrofitting and routine maintenance work, providing a standardized mounting solution for surge protection equipment.
The bracket adopts an integrated one-piece molding process with a sealed structural design. This structure delivers moisture-proof and explosion-proof properties, reducing the risk of internal moisture intrusion in long-term outdoor operation. The dedicated structural design also supports stable heat dissipation, which accommodates high overvoltage absorption during surge events.
The bracket maintains stable insulation performance with hydrophobic surface properties. This surface characteristic reduces moisture adhesion and contamination buildup on the bracket body, supporting consistent insulation performance in variable outdoor weather conditions. The design is optimized to handle operating overvoltage scenarios common in substation access points and overhead transmission lines.
With compact dimensions and light weight, the bracket supports flexible deployment across different tower configurations. It has high mechanical strength and collision resistance, allowing it to withstand normal transportation and on-site handling without structural damage. The structural design also allows for slight swinging of the mounted arrester, adapting to dynamic wind loads on overhead lines.

This insulation bracket is engineered for power line scenarios with elevated surge risk and harsh operating conditions. It is suitable for deployment in the following situations:
Overhead transmission lines with low lightning resistance levels and high lightning trip rates, supporting stable arrester installation to reduce line outage risks
Arid hilly and mountainous areas, where terrain conditions create challenges for lightning protection and grounding system performance
Towers with high grounding resistance and long-span river-crossing towers, which face higher surge impact and mechanical load requirements
Substation access points with high operating overvoltage levels, where reliable equipment insulation protection is critical for system safety
Heavily polluted areas, where the sealed structure and hydrophobic surface reduce performance degradation from airborne contaminants
For enterprise customers carrying out targeted line retrofitting projects, this bracket provides a standardized mounting solution that matches common arrester and disconnector dimensions, reducing custom design work and on-site adjustment time during construction.
This insulation bracket is compatible with standard surge arresters and lightning arresters used in medium-voltage overhead distribution systems. It supports two primary installation methods, which can be selected based on tower shape and line configuration:
Suspension mounting: Suitable for tower types that require hanging installation of arresters, allowing for controlled swinging under wind loads as permitted by design standards
Seat-type mounting: Suitable for stable fixed installation on cross-arms, for scenarios with stricter equipment displacement limits
During installation, the arrester is fixed to the upper section of the bracket, while the matching disconnector can be mounted to the lower section. This integrated layout simplifies on-site assembly and ensures proper electrical spacing between components. Commercial users are advised to confirm tower cross-arm dimensions and arrester model compatibility before placing bulk orders.
This bracket is designed as a dedicated accessory for surge arresters, lightning arresters and their matching disconnectors. It provides both insulation support and structural fixation for these devices, supporting standard installation on power line cross-arms.
The standard version of this bracket is suitable for altitudes not exceeding 2000m. For orders intended for plateau areas above this altitude, customers must specify the operating condition at the time of ordering to ensure appropriate product configuration.
Yes, this bracket is suitable for deployment in severely polluted areas. Its sealed integrated structure and hydrophobic surface help reduce the impact of contaminants on insulation performance, maintaining stable operation in such environments.
