ميزات المنتج
Reliable Electrical Insulation
The product is manufactured from high-insulation, flame-retardant material that effectively separates live conductors from surrounding components. It helps reduce the risk of electrical tracking, short circuits, and insulation failure, improving the safety of both equipment and personnel.
قوة ميكانيكية عالية
The one-piece moulded structure offers strong resistance to bending, impact, and mechanical deformation. It can provide stable support for busbars, contact systems, and other internal components during long-term equipment operation.
تركيب مريح
Four standard M10 mounting holes are integrated into the structure. The standardized mounting dimensions allow the product to be installed efficiently in compatible high-voltage switchgear, circuit breaker cabinets, and related equipment frames.
Flame-Retardant Construction
The product is manufactured from flame-retardant insulating material and includes the corresponding flame-retardant marking. Under abnormal heating or short-circuit conditions, the material helps limit flame propagation and supports the fire-safety requirements of electrical equipment.
Controlled Dimensional Accuracy
Critical contact and mounting surfaces are manufactured with controlled surface roughness, parallelism, and dimensional tolerances. This helps maintain accurate positioning, stable contact, and reliable assembly while reducing vibration and mechanical wear during operation.
Strong Environmental Resistance
The insulating composite material provides good resistance to ageing, oil contamination, electrical corona, and common indoor environmental conditions. It is suitable for long-term use in indoor high-voltage electrical equipment.

ظروف التشغيل
درجة الحرارة المحيطة
The recommended operating temperature range is:
-٤٠ درجة مئوية إلى +٨٥ درجة مئوية
The product is intended primarily for indoor high-voltage electrical equipment.
Installation Altitude
The standard installation altitude should not exceed:
2,000 metres above sea level
For installations above 2,000 metres, insulation coordination, equipment derating, or a customized product design may be required.
الرطوبة النسبية
- Daily average relative humidity: no more than 95%
- Monthly average relative humidity: no more than 90%
- Operating conditions should be non-condensing
Prolonged exposure to condensation or excessive moisture should be avoided.
Pollution Conditions
The product is suitable for indoor environments with pollution level 2 or below.
Avoid installation in locations exposed to:
- Severe dust accumulation
- Corrosive gases
- Salt spray
- Conductive contamination
- Flammable or explosive substances
- Continuous water exposure
For high-pollution or special operating environments, customized insulation measures may be required.
متطلبات التثبيت
The mounting surface must be flat, clean, and free from dust, oil, metal particles, burrs, and other contaminants.
Ensure that the product fits closely against the equipment frame without excessive installation stress. Forced installation or misaligned mounting holes may damage the insulating structure.
Use suitable standard bolts and tighten them according to the specified torque requirements. Excessive tightening may crack or deform the insulating material, while insufficient tightening may cause loosening or vibration during operation.
After installation, check the electrical clearance between live components and the insulating plate. The completed assembly should meet the applicable safety requirements for 35 kV switchgear, including the relevant requirements of GB/T 3906.
The product structure and mounting holes must not be modified without technical approval.
Inspection and Maintenance
Inspect the product regularly for signs of:
- Surface cracks
- Mechanical deformation
- Electrical tracking
- Carbonization
- Arc erosion
- Surface burning
- Severe ageing
- Loose mounting hardware
- Contamination or moisture accumulation
Replace the product immediately if cracking, serious erosion, deformation, carbonization, or significant insulation deterioration is found.
When cleaning the product, use a clean, dry, soft cloth. Do not use abrasive tools, corrosive solvents, or cleaning agents that may damage the insulating surface.
The inspection frequency should be determined according to the equipment operating conditions, environmental pollution level, and maintenance schedule.
احتياطات السلامة
This product is an insulating component and must not be installed, removed, adjusted, or inspected while the equipment is energized.
Before carrying out installation or maintenance work:
- Disconnect the equipment from all power sources
- Confirm that the circuit is fully de-energized
- Discharge any residual voltage
- Apply the required grounding measures
- Follow all applicable high-voltage safety procedures
Protect the product from impact, compression, dropping, and improper stacking during transportation and storage. Mechanical damage may reduce both its structural strength and insulation performance.
Do not drill additional holes, grind the surface, cut the structure, or otherwise modify the product without authorization.
For applications involving high altitude, severe pollution, high humidity, or other special operating conditions, confirm the required technical configuration with the supplier before installation.
