Ningbo Qiaopu Electric Co., Ltd. production LSZH power cable feed

Ningbo Qiaopu Electric Co., Ltd. developed halogen-free flame retardant polyolefin material the use of new high-power line expansion of nitrogen and phosphorus flame retardant and halogen-free advanced formula system of environmental protection made by mixing extrusion granulation, with low smoke , non-toxic, high flame-retardant, easy out, excellent mechanics and other functional advantages, the product has been through a number of state departments of technical prestige institutions function tests, fully fit domestic smoke zero halogen flame retardant cable features flame-retardant materials specification, developed by the EU ROHS Directive fit the requirements can be widely used in power cables, control cables, marine power lines, communication cables and cable insulation and sheathing materials, low smoke zero halogen flame retardant material is a traditional choice for replacement product.
The product successfully handled a halogen-free flame retardant cable estimate the fire-retardant features, functions and physical function of processing constraints conflict with each other, with six features:
First, efficient fire-retardant features
v charcoal burning speed film is good, lit the fire to reach after moving rapidly away from the self-extinguishing. Mg-Al system with flame-retardant cable materials compared to 30 company oxygen index of the product is equivalent to 35 Mg-Al system, a product of the oxygen index of flame-retardant features.
v data by the flame-retardant low smoke zero halogen cables made of wire and cable types are available through the VW-1 single vertical burning test and the rest into the bundle at all levels of combustion experiments. Single vertical burning test to reach the moving rapidly away from the fire self-extinguishing; combustion of carbon into the beam height is small, normal 0.7 meters, slightly beyond the flame height.
v smoke density when burned, in the same product in a first position.
Second, the high standard of environmental features
The product of all non-toxic non-halogen flame-retardant materials, from manufacturing to customer use, to recycling the application of the whole process all pay and green ideas, to reach low smoke, low toxicity, low corrosion, non-halogen, lead-free, sulfur-free / antimony, and the situation of people without any pollution, fit the requirements of EU environmental protection.
Third, the superior physical and mechanical features
The product features excellent physical and mechanical, tensile strength more than 14MPa, elongation at break of up to 450%, and features excellent resistance to cracking the case, special is soft in the production of large cross-section or high requirements has raised the advantages of cable , suitable for low temperature production of cables and main areas of production.
As we all know, LSZH cable jacket material in the long time (3-6 years) use of easily cracking scene showing the formation of LSZH cable materials resistant to cracking functionality of the most important cause of poor LSZH cable is estimated to add in the amount of inorganic flame retardants, anti-cracking features good or bad the situation can be characterized by the elongation at break.
Our LSZH cable materials used are high-nitrogen and phosphorus intumescent flame retardant, add a small amount, only 50% of your base material, tensile strength can reach more than 14MPa, elongation at break of up to 450% or more; and Mg-Al system LSZH flame retardant cable compound Mg added capacity, to account for more than 150% of the base material, its tensile strength elongation at break is much smaller, resistance to cracking the case is also poor.
Fourth, the superior processing capabilities
The products in various types of equipment that has versatility. No special screw extrusion and high-power motor, just the normal cooling and temperature control system can be completed on the popular high-speed PVC extrusion extruder; extrusion speed, the melt tension than good, with die easily; processing temperature limited width (130 ~ 180 ℃), good thermal stability, can be repeated repeatedly heated extrusion.
Fifth, energy saving, so that customers everywhere profits
No change from the screw and motor, the production speed of delivery, equipment wear and tear is small, the nose of recyclable materials have demonstrated the application of criteria for saving energy, so that every aspect of energy production strung, so the price is limited, energy-free limit, so that the product even more harmony with the situation
Six, convex cost
The product density of 1.02 ~ 1.07g/cm3 density between the popular LSZH information about 1.48g/cm3 your product density, comprehensive cost-raised.
