Low Voltage Cable Use Characteristics Jul 13, 2017



Low voltage cable selection:

1. First, according to the transformer capacity and connection, usually 0.4kV is Y connected, according to the capacity of 630 and 400, Low Voltage XLPE Insulated Electric Cable low-voltage output rated current is 909A and 577A;

2. According to this current as a long-term working current to choose;

3. It can also be selected by means of a long-term load and a short-term load by means of Ig = ΣIgt + K * ΣIdt (see Chapter 7 of the Power Design Manual).

Low voltage cable Use characteristics: The product is suitable for AC rated voltage 35KV and below for the transmission and distribution of electricity fixed line, the cable conductor of the highest long-term working temperature of 90 degrees, short circuit (the longest time does not exceed 5S), Low Voltage XLPE Insulated Electric Cable the cable conductor maximum temperature Not more than 250 degrees.

3. Specifications Model: 35KV and below YJV YJLV YJV22 YJLV22 YJV32 YJLV32

Low voltage cable Fire resistant XLPE insulated power cable (fire resistant high voltage cable) 0.6 / 1KV 6 / 6KV 8.7 / 10KV 8.7 / 15KV 26 / 35KV

Low-voltage cables and components The main reasons for the steady growth in market demand are the following: the process of industrialization and urbanization is accelerating, the rapid development of renewable energy, the expansion of power transmission and distribution network infrastructure and the government's strong support for power infrastructure.

Low-voltage cable market, the fastest growing areas of the Asia-Pacific region, South America, the Middle East and Africa and other developing countries concentrated areas. Low Voltage XLPE Insulated Electric Cable These areas due to the process of accelerating the industrialization and transmission and distribution network expansion needs to improve, so the growth rate is faster. Which the Asia-Pacific market will become the largest demand for regional markets. 2015, its market demand is expected to reach 42.6 billion US dollars. It is expected that by 2015-2020, the annual compound growth rate of low-voltage cable and component market in Asia and the Pacific is expected to reach 7.6%.
