Abstract

The invention discloses a cable for a variable frequency speed regulating shield machine, which comprises a cable core and a sheath layer wrapped on the outside of the cable core. The sheath layer raw materials by weight include: 100-110 parts of main materials, benzene petroleum sulfonate 1-2 parts of ester, 2.5-4.5 parts of coupling agent, 20-40 parts of pine tobacco compound, 5-15 parts of bamboo powder, 2-8 parts of aramid fiber, 3-10 parts of barium sulfate whisker, microcrystalline fiber 5-12 parts of calcium, 2-6 parts of microencapsulated red phosphorus, 0.5-1.5 parts of dioctyl phthalate, 1-1.8 parts of microcrystalline paraffin, 1-2 parts of UV absorber RMB, acrylonitrile-butanedi 1-2 parts of ethylene-styrene copolymer. The invention can resist tensile, deformation and external force, and has excellent weather resistance and durability, can protect the metal material inside the cable for a long time, prevent oxidation corrosion, and also has very high mechanical strength.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for a variable-frequency speed-regulating shield machine. Background technique [0002] Frequency conversion speed regulation technology has the advantages of low noise, low energy consumption, stable speed regulation, reliable low-speed operation, etc., and has been applied more and more in various industries. The cable for the shield machine is one of the key accessories of its equipment, and it is the connection line for the power supply and control signal transmission of the shield machine. The shield machine is frequently started, and the speed is complicated. The cables are dragged, bent, vibrated, torsion, and ore impacted. The operating environment is complex, and the requirements for the safety and functionality of the cables are high. How to prepare a tear-resistant, impact-resistant cable needs to be solved urgently. Contents of the invention [0003] Based ...
