1、Extrusion: CPE has good heat-resistant and processing capability and wide extrusion temperature range, which enhance the safety for processing. For its hardness and viscosity are higher than neoprene, its extrusion temperature is correspondingly higher by 5-10 degrees.
Temperature range for stuffing port: 40-50℃
Temperature range for machine body:55-70℃
Temperature range for machine head: 65-80℃
2、In practical production, according to the difference of extruding machine and cable diameter, the processing parameter shall be adjusted. We will provide relevant technical data to our consumers after they buy our products and send experienced technicians to give on-site guidance.
3、Storage: it can be stored for more than six mouths. And it can still be used even though hardened after long time storage. It should be better for recycling if the conditions allows. Keep away from direct sunlight and raining.
Low-smoke halogen-free materials can reduce the toxic and corrosive gases produced during combustion. In poorly ventilated environments such as airplanes, train cars or ships, low-smoke and halogen-free materials are often used. Low-smoke halogen-free materials are also commonly used in the railway industry or shipbuilding industry. It is important to protect personnel and equipment from toxic and corrosive gases. The use of low-smoke halogen-free materials can also reduce the accumulation of toxic gases when the circuit is damaged due to fire or short circuit.
Natural rubber has high elasticity at room temperature, is slightly plastic, has very good mechanical strength, low hysteresis loss, low heat generation during multiple deformations, so its flex resistance is also very good, and because it is non-polar Rubber, so the electrical insulation performance is good. SBR has the advantages of wear resistance, cold resistance, low heat generation, low shrinkage, good color, less ash, high purity and fast vulcanization speed, and has the advantages of low rolling resistance, excellent wet-slip resistance and wear resistance. , With a wide range of applications.In addition, styrene butadiene rubber has the advantages of good touch, good weather resistance, good resilience and small permanent deformation.
The main application field of the submersible pump cable is used in oil wells. The environment in the oil well is very poor. It is always in a high temperature and high pressure state. Because of the large amount of oil and gas, it is very corrosive to the things in the well. Submersible pump cables can be divided into two types: round and flat. Restricted by the size of casing space in oil wells, generally the power cables of submersible pumps are mainly flat. Because the flat cable has an asymmetric structure, when power is transmitted, the electromagnetic induction caused by the unbalance of the magnetic field will cause hysteresis loss and heat the cable. Round cables should be used when the casing size of the oil well allows. The electromagnetic field generated by the symmetrical circular cable is evenly distributed, with little interference with each other, and good electromagnetic compatibility. It is very convenient to build in oil wells.
