Phosphorus bronze four-color low-temperature cable

Phosphorus bronze four-color low-temperature cablePhosphorus bronze low-temperature wire exhibits significant performance in low-temperature applications, especially in harsh environments. The main focus includes: high conductivity and resistance stability: in ultra-low temperature environments such as liquid helium (0.1mK) to liquid nitrogen (325K), the conductivity remains above 98%, and the resistivity fluctuates<± 1.5%; The resistance change rate in the wide temperature range of 0.1mK to 325K is less than 3%, and the quality is higher than that of ordinary copper materials. Corrosion resistance and chemical inertness: Strong resistance to acids, alkalis, and organic solvents, and the surface oxide layer can resist moisture or salt spray erosion, extending the service life.

Fatigue resistance and wear resistance: The structural integrity is maintained after repeated bending, and no sparks are generated during impact, making it suitable for vibration or mechanical stress environments.

Non ferromagnetic and low-noise: effectively reduces electromagnetic interference noise and improves signal transmission accuracy.

High heat resistance and insulation performance: The outer polyimide insulation film has a long-term temperature resistance of over 325K, an instantaneous temperature resistance of over 573K, and a thermal conductivity of 48W/(m · K), ensuring thermal balance and protection.

Thin and high-strength design: The insulation layer thickness is only 0.05-0.1mm, with tear and puncture resistance, avoiding the risk of short circuit.

Phosphorus green copper wire is suitable for almost all low-temperature applications, and its low magnetic resistance makes it an ideal choice for magnetic field applications

Four strand low-temperature cable

36 AWG is a 4-wire "ribbon cable" that makes it easier to dissipate heat and trim leads compared to using a single wire. It is easy to make non inductive (double wire) windings using four lead wires for heat sinks and heaters. In addition, the wires are color coded with black, gold, red, and green for easy identification of the leads, and can be split into 2 pairs. Due to its low magnetic resistance, four lead wires can also be used for standard four lead measurements in magnetic field applications.

Four twisted low-temperature wire

Four stranded wire is a twisted pair of 32 or 36AWG phosphor copper wires Each pair of wires has 3.15 twists per centimeter (8 twists per inch), and 2 pairs of wires are twisted together at 1.57 twists per centimeter (4 twists per inch). This type of wire is a great choice for diode sensors and sample testing, as it can minimize the induced current generated by the wire. Using one pair of twisted wires to apply current to the sensor and the other pair of twisted wires to measure the output voltage of the sensor can minimize electromagnetic noise.
