Cable Accessories

Cable accessories series products, its rated voltage is 8.7/15kv, rated current 630A. Mainly applicable to all kinds of European box transformer, ring network cabinet, cable branch box and other electrical equipment. Flame retardant series cable accessories have obtained national invention patents and utility model patents. Superior flame retardancy can disconnect the power supply before the accident, and automatically disconnect the power supply after the product burns, which will not ignite other accessories, thus avoiding the devastating accident of the whole machine.

Product Parameters

Performance characteristics

 

1. Adopt advanced production technology: adopt automatic injection and multi-layer composite molding process to make the product performance reach the international advanced level.

2. Three-layer protective structure: The semi-conductive layer of the insulating layer is based on high-quality EPDM rubber raw materials, and the patented rubber formula developed independently has excellent electrical insulation performance and corona resistance.

3. Material characteristics: weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, aging resistance, corrosion resistance, excellent electrical insulation and corona resistance and physical and mechanical properties, good sealing performance.

4. Product characteristics: strong temperature resistance, can not change the power frequency withstand voltage, local discharge capacity of the electrical properties at 150 ℃. 5. Strong airtightness, can withstand pressure in water, and does not change the electrical performance after soaking for 72 hours.

6. Flame retardant characteristics: after full combustion, the fire source is disconnected and extinguished within 2s, and the flame retardant grade is V0.
