1. Product Overview<\/h2>\n<\/div>\n
\n

Pendahuluan<\/h3>\n<\/div>\n
\n
FCGW-20\/24kV composite dry wall bushing is a core insulating component designed for 24kV medium voltage power systems, used to guide high-current conductors through the wall between indoor switchgear rooms and outdoor power distribution areas.<\/p>\n
<\/div>\n

Adopting advanced silicone rubber composite insulation structure, this dry-type bushing abandons traditional oil-filled design, featuring lightweight, pollution-resistant, explosion-proof, maintenance-free performance.<\/p><\/div>\n

Widely applied in power substations, ring main units, high-voltage switch cabinets, transformer stations and industrial power distribution projects.<\/div>\n<\/div>\n

                \n
                  \n
                1. Reserve matching square wall opening according to the flange drawing size before wall construction.<\/li>\n
                2. Place the bushing through the wall opening, align the flange fixing holes with wall embedded bolts.<\/li>\n
                3. Tighten fixing nuts evenly to fix the bushing vertically to the wall.<\/li>\n
                4. Connect indoor and outdoor copper busbars to the two ends of the bushing conductive core, use anti-oxidation conductive grease at the joint to reduce temperature rise.<\/li>\n
                5. Check silicone rubber insulation surface for damage before power transmission, keep creepage surface clean without dust accumulation.<\/li>\n<\/ol>\n<\/div>\n

                    7. FAQ<\/h2>\n<\/div>\n
                    \n

                    Q1: What is the difference between 760mm height and 840mm height models?<\/h3>\n<\/div>\n
                    \n
                    A: 760mm height for 400A\u20131600A medium current, shorter indoor creepage; 840mm height for 2000A\u20134000A heavy current, thicker copper conductor and longer indoor insulation creepage to control temperature rise under high load.<\/div>\n<\/div>\n
                    \n

                    Q2: Can this bushing be used in coastal salt fog areas?<\/h3>\n<\/div>\n
                    \n
                    A: Yes. The silicone rubber composite material has excellent hydrophobicity and anti-salt-fog performance, suitable for coastal, chemical plant and high-pollution environments.<\/div>\n<\/div>\n
                    \n

                    Q3: Is the product oil type or dry type?<\/h3>\n<\/div>\n
                    \n
                    A: Full dry composite structure, no insulating oil inside, no leakage hazard, meets environmental and fire safety requirements for indoor power distribution rooms.<\/div>\n<\/div>\n
                    \n

                    Q4: Can you provide CAD dimension drawings for design reference?<\/h3>\n<\/div>\n
                    \n
