Waterproof and explosion-proof intermediate joint box

Intermediate joint boxes with waterproof and explosion-proof features are available in FRP and SMC materials, with models such as VB-1600-125-70, VB-1620-255-125, and WOER 10KV SMC boxes for high-voltage cable protection. Key Models and SpecificationsFRP Explosion-Proof Boxes (VB Series): Designed for single-core and three-core cables, suitable for 10kV to 35kV applications. Common models include VB-1600-125-70, VB-1600-140-80, VB-1620-255-125, and VB-2300-280-125.

These boxes feature a glass fiber reinforced plastic shell, silicone rubber sealing rings for enhanced waterproofing, and a boat-shaped upper and lower structure for durability and explosion containment.

SMC Explosion-

Proof Boxes: Made from Sheet Molding Compound (SMC), these boxes provide high-strength, corrosion-resistant, and flame-retardant protection. They are suitable for harsh environments, including outdoor cable trenches and chemical sites. Examples include the WOER 10KV Cable Intermediate Joint Fire Explosion Proof Box, with a length of 1200mm and inner cavity diameter of 180mm, rated for 10kV applications.

Aluminum Alloy Explosion-

Proof Junction Boxes: For lower voltage applications (220V/380V), these boxes offer IP65 protection, waterproofing, dustproofing, and corrosion resistance, suitable for chemical, oil, and gas industries. They feature customizable entry points and terminal blocks, with housing made from aluminum alloy die-casting or welded steel plate. Material and Performance FeaturesFRP (Fiber Reinforced Plastic): High flame retardancy (oxygen index 62.

5%), corrosion resistance against acids, alkalis, salts, and oils, suitable for long-term burial and coastal environments.

SM

C (Sheet Molding Compound): Excellent explosion-proof capability, corrosion resistance, UV protection, and temperature tolerance from -50°C to 150°C, with IP55 protection level. Sealing and Waterproofing: Silicone rubber rings and internal filling materials enhance waterproof performance and prevent secondary damage during cable joint failures. ApplicationsHigh-voltage cable intermediate joints in power distribution networks, substations, and industrial installations.

Environments with harsh weather, chemical exposure, or risk of explosion. Both indoor and outdoor installations, including cable trenches, wells, and offshore platforms. These models provide robust protection against fire, explosion, moisture, and environmental stress, ensuring the safety and longevity of critical cable connections in high-voltage systems.
