Summary of the invention
To solve the above-mentioned problems, the utility model discloses a kind of novel flame-retardant water proof type photovoltaic cables.
The utility model is achieved through the following technical solutions:
A kind of novel flame-retardant water proof type photovoltaic cable, the cable include several conductors, the outer extruded insulation layer of the conductor
Insulated wire cores are constituted, around galvanized steel strip composition armor, the insulating layer and the institute of double-baging after the insulated wire cores twisted synthesizing cable
It states filled with fire-proof mud between armor, the armor is coated with erosion resistant coating, is surrounded with fireprotection layer outside the erosion resistant coating, institute
It states fireprotection layer and is externally provided with oxygen barrier layer, the oxygen barrier layer is coated with waterproof membrane, oversheath is extruded with outside the waterproof membrane.
The insulating layer is extruded by heat curing type polyolefine material.
Erosion resistant coating is made of fluorubber material.
The fireprotection layer is formed by fire-resistant isinglass belt is wrapped.
The oxygen barrier layer is magnesia oxygen barrier layer.
The oversheath is that thermoplastics type is halogen-free and low-smoke flame-retardant polyolefin sheathed.
Compared with prior art, the utility model has the beneficial effects that
The utility model photovoltaic cable structure novel, the outer wall of insulating layer are wound with armor, to increase the machinery of cable
Intensity improves erosion prevention, while can also extend the service life of cable；Filled with fire prevention between insulating layer and armor
Mud, fire-proof mud play fire-retardant and oxygen-impermeable effect, avoid fire spreading；The outer wall of armor is equipped with erosion resistant coating, increases cable
Anti-corrosion effect；Fireprotection layer and magnesia oxygen barrier layer are set gradually outside erosion resistant coating, when the outer layer of cable is ignited, magnesia every
Oxygen layer is not melted non-ignitable hard shell by thermosetting, plays the role of cooling and isolation, and fire spreading is avoided to cause bigger economic damage
It loses, good flame retardation effect.
