Description

technical field

[0001] The invention relates to an insulating material for cables, in particular to a radiation-crosslinkable halogen-free flame-retardant insulating material for photovoltaic cables; it belongs to the technical field of new cable materials. Background technique

[0002] With the sharp reduction in the production cost of polysilicon, the raw material of solar cells, and the improvement of solar cell production technology, the output of solar cells in the world has increased very rapidly in recent years, which is called a sunrise industry. According to statistics, the annual output of solar cells in the world was 387 megawatts in 2000, 540 megawatts in 2002, 742 megawatts in 2003, 1195 megawatts in 2004, and 1700 megawatts in 2005, with an annual increase of 30%. ~60%. The market demand for photovoltaic cables for solar cells is also growing rapidly.

[0003] Since photovoltaic cables are often used under harsh environmental conditions, such as high and low ...
