Inorganic Sheathed cables

What are the main structural layers of Inorganic Sheathed cables?
1. Conductor (Core)
Single-core or multi-core copper wire is used. The core material can be TU2 oxygen-free copper or copper wire coated with austenitic stainless steel, ensuring excellent conductivity and corrosion resistance.
2. Metal Shield (Sheath)
TU2 copper coated with austenitic stainless steel or stainless steel provides strong electromagnetic shielding and mechanical protection, suitable for high-radiation environments such as nuclear power plants.
3. Inorganic Sheathed cables
High-purity mineral materials such as aluminum oxide, magnesium oxide, or silicon dioxide are used. They offer high-temperature resistance, flame retardancy, and radiation resistance, making them key to cable durability.
4. Multi-layer Structure (Optional)
Multiple insulation layers can be placed between the metal shielding layers to achieve higher signal integrity and safety redundancy.
How is field splitting or splicing performed?
1. Field Cutting
Use specialized cutting tools to precisely cut the outer sheath to avoid damage to the internal metal shielding and insulation. The cut should remain smooth to facilitate subsequent splice installation. 2. Removing the Metal Shield
Manually or mechanically remove the metal shield, ensuring that the internal mineral insulation layer is not damaged. If necessary, use anti-static tools to prevent static discharge.
3. Insulation Treatment
Clean the exposed Inorganic Sheathed cables layer using a specialized cleaner to remove dust and oil, ensuring the connector end faces are clean and free of impurities.
4. Connector Installation
Use nuclear-grade metal connectors or crimp connectors. Use a high-temperature, radiation-resistant sealant or epoxy resin for secondary sealing to ensure long-term reliability in high-temperature, radiation-resistant environments.
