Abstract
The invention discloses a non-magnetic field armored signal cable in the technical field of signal cables. The non-magnetic field armored signal cable includes a non-magnetic metal core. A magnesium oxide cylinder sleeves the surface of the non-magnetic metal core wire. A filling layer is fixedly connected at the interlayer between the non-magnetic metal core wire and the magnesium oxide cylinder,the surface of the magnesium oxide cylinder is fixedly connected with a non-magnetic austenitic stainless steel pipe, the surface of the non-magnetic austenitic stainless steel pipe is fixedly connected with a fireproof layer, and the surface of the fireproof layer is fixedly connected with an antirust layer. Through cooperation of the non-magnetic metal core, the magnesium oxide cylinder and thenon-magnetic austenitic stainless steel pipe, the non-magnetic field armored signal cable is wide in temperature measuring range, is shock resistant and high temperature resistant, and produces temperature difference electric potential during temperature measuring. A magnetic field generated by an inner core of the cable disappears due to the rotary twisted pair shape, signals of the cable will not be interfered, and the external diameter and the size of the cable can be set freely.
Description
technical field [0001] The invention discloses a magnetic field-free armored signal cable, and specifically relates to the technical field of signal cables. Background technique [0002] A signal cable is a signal transmission tool. Generally, the signal transmitted by the signal cable is very small. In order to avoid signal interference, there is a shielding layer outside the signal cable. The shielding layer of the wrapped conductor is generally conductive cloth, braided copper mesh or copper mooring (aluminum), and the shielding layer needs to be grounded. External interference signals can be guided into the ground by this layer, preventing interference signals from entering the inner conductor and reducing the loss of transmission signals. The existing signal cable transmission signal is weak and the manufacturing process is complicated. Therefore, in recent years, many experts in my country have done a lot of research on how to realize a large number of zero-magnetic f...
