JDG/KBG Conduit

JDG conduit full name is Sleeve Tightened Galvanized Steel Electrical Conduit, complying with standard CECS120:2007, widely used for electrical wiring protection in commercial buildings, data centers and fire-fighting weak current projects. Material & Standard Specifications Made of Q195/Q235 cold rolled steel strip, high-frequency welded and double-sided hot-dip galvanized inside & outside for anti-corrosion. Standard wall thickness: - Φ16: 1.2mm - Φ20/25/32/40/50: 1.6mm Standard length: 3m, 4m, 6m; custom cutting available. Complete Fittings Straight coupling, box connector, elbow, lock nut, set screw, bending spring, grounding clip. Key Advantages 1. Easy & safe installation: No welding, no threading, no separate grounding jumper. Only tighten set screw with special wrench to lock tubes, no open flame on construction site. 2. Excellent fire resistance: Non-combustible metal material, prevents cable short circuit & flame spread, passes fire inspection. 3. Strong electromagnetic shielding: Blocks signal interference, stable for monitoring, network & intelligent wiring. 4. High mechanical strength: Anti-extrusion & impact resistant, not easy to deform when embedded in concrete. 5. Long service life: Uniform hot-dip galvanized layer, moisture & rust proof, service life over 50 years for indoor & damp basement. 6. Good tightness: Tight sleeve connection stops dust & moisture from entering to protect cables. Application Scenarios Indoor surface mounting, ceiling laying, wall/floor embedding; suitable for office buildings, shopping malls, hospitals, data rooms, high-rise residential buildings, fire alarm & intelligent weak current systems. Not recommended for long-term outdoor exposure or heavy acid-alkali corrosive workshops (stainless steel conduit as alternative). Difference between JDG / KBG / SC Conduit 1. JDG (Screw Tight Type): Thick wall, reliable conductive connection, no extra grounding, ideal for commercial & fire-fighting projects. 2. KBG (Crimp Type): Thin wall, poor continuity, only for simple household lighting, prohibited for fire systems. 3. SC Welded Conduit: Heavy thick wall, requires threading & welding grounding, used for civil air defense & underground buried pipelines with high cost.
