Product Description
1 General Introduction
1.1 Feature on Structure
The DFW series cable distribution cabinet (called the product in the following) using the SF6 load switch or vacuum circuit breaker as a control switch(can select this configuration or not )and including the flood-protection & shielded cable terminals which made by silicone rubber that can be touched when the cable is living. The product have a strong short-circuit making capacity and breaking capacity while active-power load or no-load. We also can configurate arrester & earth fault indicator according to customer's requirements. In the product of this series: every connecting line of RMU can configurate load switch or vacuum circuit breaker, every branch circuit can quit or join the operating freely, and the other ring network circuit would't be affected; Fuse can be assembled on the load switch , while the short-circuit occurred in one branch circuit, the fuse will break the fault circuit and heat the tripper of load switch to break the circuit causing the fault circuit be isolated, so that the continuity of un-fault branch circuit will be guaranteed. 1.2 Application
The cable distribution cabinet is widely used in the cable branching of 10kV power system. When the product is combined with the power cable, it can be provided with flexible configuration, convenient installation, high safety and reliability, simple maintenance, and is convenient to feed and distribute power to the users. The products are widely used in secondary substation, industrial park, housing district, business district, airport, railway, and the other distribution network. It's very suitable for renovation project of city railroad power-grid that can save more investment on electric equipment & cables and improve the reliability of distribution also. 1.3 Service Condition
