| Abstract: | According to the product standards, design codes and laying regulation, the three technical features of mineral insulated cable that influence its economical efficiency are discussed in details, i.e., large current-carrying capacity; capable of direct laying without requirement of cable conduit, concealed laying in walls or laying on fire-proof cable trays; copper sheath can be grounded directly, thus saving one protection grounding conductor. In comparison with mica and plastic insulated fire-resistant cable, it is demonstrated that it is more economical to use mineral insulated cable. |
