Ang DC 75 kV dust filter cable terminal usa ka espesyal nga cable accessory gamiton sa high-voltage direct current transmission systems. Ang iyang mga teknikal nga karakteristika ug struktural nga disenyo mao kini:
1. Core structure and materials
Ceramic sleeve design: Nagpadayon og high-strength ceramic umbrella skirt stacked structure, may sukad nga 500mm ug umbrella skirt crawling distance mas dako sa 1260mm, aron makapadali sa insulation performance sa high voltage
Stress cone component: usa ka integral silicone rubber molded part nga nagpakita og tight fit uban sa cable insulation layer, optimizasyon sa electric field distribution
Sealing system: Tanang interfaces gigamit og silicone rubber sealing rings, may cross-sectional area to embedded U-shaped groove ratio nga 1.2-1.3:1, abilidad sa long-term waterproof ug moisture-proof
2. Performance advantages
Mechanical strength: Elastic sealing nahitabo pinaagi sa cold shrinkage ug pre-expansion technology, may quick installation ug tight fit
Environmental adaptability: May excellent corrosion resistance, high temperature aging resistance, ug angay sa harsh outdoor environments
Maintenance cost: Long overall lifespan, low maintenance frequency, naka-reduce sa operation ug maintenance costs
3. Typical applications
Medium and low voltage transmission system: angay sa DC 75kV voltage level, kasagaran gigamit sa substations, cable terminal connections ug uban pang scenarios
Supporting equipment: Makagamit usab kini sa GIS combination appliances o transformer interfaces, ug importante ang standardized matching sa installation flanges
