Description
Technical field
This utility model relates to solar photovoltaic technology field, and especially a kind of photovoltaic plant is straight with low temperature resistant boundling
Stream aluminium alloy cable.
Background technology
According to " planning of regenerative resource Long-and Medium-term Development ", to the year two thousand twenty, China strives making solar electrical energy generation installed capacity
Reach 1.8GW(gigawatt), it is up to 600GW(gigawatt to the year two thousand fifty).Before anticipated the year two thousand thirty, China's solar energy dress
The compound growth rate of machine capacity will be up to more than 25%.Owing to photovoltaic power station component arrangement areas is big, the DC side progression that confluxes is many,
Direct current number of cables of confluxing is huge, and therefore cost accounting is higher.
At present, the dc main cable of domestic and international photovoltaic plant, mostly use general low-voltage alternating-current cable to replace, conventional
Model is ZR-YJV22 0.6/1kV, ZR-YJY23 0.6/1kV, and cable great majority are copper core cable.Due to ac cable
Field intensity stress distribution is equilibrium, and cable insulation material is it is important that electric medium constant, and electrolyte is not temperature influence；And it is straight
The stress distribution of stream cable is the exhausted internal layer of cable for maximum, is affected by the resistance coefficient of cable insulation material, and insulant has negative
Temperature coefficient phenomenon, i.e. temperature increase, and resistance diminishes；Operationally, core loss can elevate the temperature cable, the insulation of cable
The resistance coefficient of material can change therewith, and the electric field stress also leading to insulating barrier changes therewith, say, that same thickness
Insulating barrier, owing to temperature raises, its breakdown voltage diminishes therewith.For the dc main in some distributed power stations, due to environment
The height change of temperature, the speed that the insulant of cable is aging is more much bigger than the buried cable laid, and therefore uses low pressure to hand over
Stream cable replaces the dc main cable of photovoltaic plant to use certain potential safety hazard.
In prior art, the conductor of cable uses the aluminum alloy materials of price more advantage；And cable has low temperature resistant
Run, transmission capacity is big, good bending property and the electric stability four big strength advantage of safety: cable conductor length is short, resistance
Little, cable is little without filling, thermal resistance；It addition, this product possesses more preferable bending property, its cable minimum bending radius is 15 times
Cable short side dimension, compared with two core twisted cable structures, bending radius can narrow down to about 60%；Still further, this product possesses
Safer electric stability, according to load after a diameter of 20 times of flat cable short side dimension bending processes, at conductor 105 DEG C
Cyclic test, impulse voltage test and the test of 1.85kV/2h DC break down voltage subsequently do not puncture.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that a kind of photovoltaic plant is with low temperature resistant boundling direct current
Aluminium alloy cable, thus make it have that purchase cost is low, transmission capacity big, good bending property, environmental suitability are strong, lower temperature resistance
The feature that energy is good, creep-resistant property is excellent.
The technical scheme that this utility model is used is as follows:
A kind of photovoltaic plant low temperature resistant boundling direct current aluminium alloy cable, including aluminium alloy conductor, described aluminium alloy conductor
