Overview
With the rapid development of China's national economy, electricity and lighting demands of subways, airports, tunnels, bridges and buildings that are building in all major large and medium-sized cities all have an urgent need: power transmission and distribution lines that both comply with environmental protection requirements and can adapt to the characteristics of the above-mentions buildings.。
To meet market demand, Shanghai SOCO Group New Product Research Institute has specially developed large-section armored multi-core prefabricated branch cables in line with the environmental requirements, which have been put into mass production. The type and specification includes: Common type, cross-linked, flame-retardant, fire-retardant, safe and clean type, oxygen barrier flame-retardant and fire-retardant. Maximum cross section of the cable up to 240mm2/phase; branch sections can be produced according to user requirements.

Note: The remaining parameters are same that of similar power cables (VV, YJV), and power cables with same sections or same number of cores.
Description: Rated currents of VV and YJV type cables are the data when laying in the following standards.
(1) VV plastic insulation
a. Maximum working temperature of conductor = 70 ℃ b
b. Ambient air temperature =40 ℃
c. Ground temperature is over 25 ℃
d. Soil thermal resistance =1.0Km / W
e. Underground laying depth= 0.5m
(2) YJV insulation
a、Maximum working temperature of conductor = 90 ℃ b
b、Ambient air temperature =40 ℃
c、Ground temperature is over 25 ℃
d、Soil thermal resistance =1.0Km / W
e、 Underground laying depth= 0.5m
