With the development of spring application technology, many new problems need to be paid attention to and solved for designers. For example, the influence of material, high pressure and shot peening on fatigue performance and relaxation performance is difficult to calculate accurately during design; it depends on experimental data; another example is the number of turns calculated according to the current design formula, and the spring stiffness is higher than the design. If the stiffness value is small, it is necessary to reduce the effective number of turns to meet the design requirements.
The use of spiral cables is necessary in almost all industries. Whether in communications (telephony, radio) or medical technology, the electric locomotive industry, mechanical engineering, or in the lighting industry, Shanghai spring coiled cables are used everywhere. In addition to the electro-mechanical advantages, helical cables are often an excellent optical structural solution. If you use PVC and PUR cables, the color of the spiral cable can in most cases match the color of the object. At the same time we can also supply: shielded spiral cable. Spiral spring cable series, spiral cable for instrumentation, spring wire for automotive power supply, spiral cable for transformer power supply, spiral cable for large electromechanical equipment, spiral cable for cleaning machine power supply, special 5-core spring wire for automatic billing of electric meters, etc.
Scope of application: used for rated AC voltage 450/750V or DC voltage below 6V-1000V, need to go back and forth. Assembly circuits that move up and down are assembled and wired, such as telephones, computers, electronic equipment by plug-in and automobile, trailer, spring connection lines.
Product features: It has good flexibility and elasticity (the elongation length can reach 2-3 times of the original spring length). It has good cold resistance, flame resistance, oil resistance and abrasion resistance. Various types of helical spring wires can be produced according to different requirements of the occasion.
Conductor structure: Use single-strand or glued bare soft copper wire (or tinned copper wire Insulation material: Polyoxyethylene, polyethylene, Hangzhou spring polyethylene or joint polyethylene can be used to meet the requirements of different occasions.
Sheath material: generally use flame retardant polyurethane elastic material PU material Working temperature: according to customer requirements, cold resistance -65 degrees; temperature resistance 80 degrees. 105 degrees. 125 degrees production range: standard section: 0.12 ~ 4 square meters (special specifications can be produced according to customer requirements).
Number of electric diameter cores: 1 to 37 cores (special specifications can be produced according to customer requirements).
