I. Visão Geral do Produto
The ZJ-10Q/65 *140 column insulator is an insulating support component specifically designed for indoor high-voltage power distribution scenarios. It is molded using an epoxy resin vacuum casting process, resulting in a compact structure and small size, while possessing excellent insulation performance and mechanical strength. This product is mainly used in 10kV power distribution systems to provide insulation and fixation for electrical equipment such as busbars, switches, and fuses, effectively ensuring the normal operation of electrical equipment and eliminating safety hazards such as leakage and short circuits.
II. Core Product Features
- Excellent insulation performance : Made with high-quality epoxy resin raw materials and processed by vacuum casting, the insulation layer is dense and non-porous. The power frequency withstand voltage and lightning impulse withstand voltage strictly meet the relevant national standards. It has high insulation reliability and can effectively resist transient overvoltage impulses, avoiding the risk of insulation breakdown.
- Outstanding mechanical strength : The product has a reasonable overall structural design, strong bending and impact resistance, and a bending failure load of up to 40kN. It can withstand the mechanical stress generated during the operation of power distribution equipment, ensuring that it will not break or deform during long-term use and guaranteeing the stability of the equipment.
- Strong weather resistance and adaptability : It has good resistance to dirt and moisture, and can adapt to the normal indoor working environment without complicated maintenance measures, reducing the user’s operation and maintenance costs; at the same time, it can be adapted to condensation and Class II pollution environments, making it applicable to a wider range of scenarios.
- Easy and reliable installation : Standard threaded holes are provided at both ends of the product to accommodate conventional installation accessories. The installation process is simple and efficient, requiring no special tools. The connection is firm and reliable, effectively preventing loosening or displacement during equipment operation and ensuring the stability of the power distribution system.
- Long service life : Epoxy resin materials have excellent aging and corrosion resistance, and are not easily affected by environmental factors and will not age or deteriorate. Under normal use, the service life can reach more than 15 years, reducing the frequency of product replacement and usage costs.

IV. Âmbito de Aplicação
4.1 Cenários Aplicáveis
This product is a high-voltage insulation support component specifically designed for indoor use. It is mainly used in 10kV indoor power distribution systems, and its specific applications include:
- Internal insulation support for various indoor switchgear, distribution cabinets, and prefabricated substations;
- The 10kV busbar is supported and fixed to achieve insulation isolation between the busbar and the cabinet, and between the busbar and other equipment;
- Insulation fixing and installation of electrical components such as switchgear, fuses, and transformers;
- In other 10kV indoor power distribution scenarios, the parts that require insulation and mechanical fixing.
4.2 Equipamento Compatível
It can be directly adapted to conventional 10kV indoor switchgear such as XGN2, KYN28, XGN66, and GGD. Customized adaptation solutions can also be provided according to users’ special installation requirements.
V. Usage Conditions
To ensure normal operation and extend the product’s lifespan, it must be used under the following conditions. If the conditions exceed these limits, please contact the manufacturer in advance and take appropriate protective measures:
- Ambient temperature : -10℃ ~ +40℃. Avoid prolonged exposure to extreme high or low temperatures (exceeding this range can easily lead to insulation aging and decreased mechanical properties).
- Altitude : Not exceeding 1000m. When the altitude exceeds 1000m, the product parameters need to be adjusted according to the altitude to avoid the insulation performance being affected by air pressure.
- Relative humidity : Daily average relative humidity ≤95%, monthly average relative humidity ≤90%. Avoid prolonged exposure to high humidity and severe condensation environments (to prevent a decrease in insulation performance).
- Condições ambientais : The operating environment must be free from obvious dust, corrosive gases (such as acids, alkalis, salt spray, etc.), flammable and explosive media, and severe vibration; if a corrosive environment exists, anti-corrosion protection measures must be taken.
- Dirt level : It is suitable for condensation and Class II dirt environments by default. If it is used in Class III or above dirt environments, a special anti-fouling product must be selected.
- Installation angle : Vertical installation is recommended, with an installation angle deviation not exceeding ±5°, to avoid mechanical stress concentration caused by tilted installation.
VI. Precautions for use
- Before installing the product, check its appearance for any defects such as cracks, breaks, or missing pieces. If any defects are found, do not use the product.
- During installation, appropriate bolts and nuts should be selected according to the product installation dimensions, and the tightening force should be moderate to avoid over-tightening that could damage the product.
- During product use, the condition of the insulation layer needs to be checked regularly. If aging, cracking, or damage is found in the insulation layer, it should be replaced in time to avoid insulation failure.
- It is strictly forbidden to apply corrosive substances such as oil or paint to the product surface to avoid damaging the insulation layer;
- When storing products, they should be placed in a dry, ventilated, and cool warehouse, away from humid, high-temperature, and corrosive environments. The stacking height should not be too high to prevent damage from compression.
- The product must not be used beyond its rated parameters. If it is necessary to change the usage conditions or parameters, it is necessary to confirm with the manufacturer in advance. It is strictly forbidden to change the product structure or parameters without authorization.
VII. Maintenance and Care
1. Routine maintenance: Conduct an appearance inspection of the product every six months, clean the surface dust and debris, and check whether the installation is secure and whether there is any loosening or displacement;
2. Regular testing: Conduct insulation performance testing on the product once a year to ensure that parameters such as power frequency withstand voltage and insulation resistance meet the standards;
3. Troubleshooting: If insulation breakdown, mechanical damage, or other faults are found in the product, it must be stopped immediately, replaced with a new product, and the cause of the fault must be investigated to prevent the fault from escalating.
4. Maintenance cycle: Under normal conditions, a comprehensive maintenance should be performed every 1-2 years; in dirty or humid environments, the maintenance cycle should be shortened to once every 6 months.
