Four Core Parallel Bundling Aerial Insulated Cabling

Four core parallel bundling aerial insulated cabling
The parallel bundle conductor adopts three-phase four-wire power supply, so that the unbalanced degree of the three-phase load reduce to small, the neutral line current is reduced, and the resistance loss is reduced. Due to the adoption of the close type symmetrical split structure, the inductance of the conductor is reduced, the dielectric constant of the wire is increased, the capacitance is increased, and the reactance of the circuit is reduced, and the purpose of reducing the loss and the expansion is realized.
 
Four core parallel bundling aerial insulated cable model:
 
0.6/1KV JKLVS aluminum conductor PVC insulated overhead bundle conductor, overhead laying, service drop wire, etc.
 
JKLYS aluminum conductor PE insulated overhead bundling wire, overhead laying, service drop wire etc.
 
JKLYJ aluminum core XLPE insulation overhead bundle conductor, overhead laying, service drop wire, etc.
 
Purpose:
 
Bundle conductors (parallel bundle overhead insulated cables), are used in township, markets, relatively narrow rural street, alley and residential places, because of its low line loss, construction is simple, time-saving, labor-saving, combination of tensile breaking force is strong, high safety, anti-theft, prevent leakage, and low construction cost, in the vast rural power transformation and construction has been popularized used.
 
Main technical index of cable:
 
1. The conductor of the cable adopts aluminum core coarct stranded circular conductor, the relevant provisions of the coarcted  round stranded conductor shall be in accordance with the GB/T3956-1997(IEC60502).
 
2. The insulation adopts black PVC, PE, XLPE weather-proof insulating material.
 
3. cables adopt AC voltage test:
 
Rated voltage 0.6/1KV and below cable shall withstand 3500V, 1min flooding pressure test.
 
4. cable surface has clear manufacturer name, type, length and voltage level.
