Problems solved by technology

[0002] EPDM rubber is widely used as wire and cable insulation materials because of its excellent electrical properties, high heat resistance and aging resistance, and good low temperature flexibility. However, the insulation properties of different formulations of EPDM rubber vary greatly.
[0003] Ship hydrophone equipment needs to use waterproof shielded rubber cables. Due to long-term work underwater, seawater is very corrosive to cables, so the cable insulating rubber is required to have good waterproof and insulating properties. Currently, there is no special cable in the festival field Cables used for ship hydrophone equipment, non-special cables used in this environment have poor waterproof performance and short service life
