Zusammenfassung:The invention discloses a PVC cable with long-acting hot water resistance, and application thereof. The PVC cable is composed of PVC powder with the polymerization degree of 1300, a hydrophobic filler, a plasticizer TOTM, oxidized polyethlene wax, antimony trioxide, a calcium-zinc composite stabilizer and CPE-135A. The main material and the auxiliary material are both materials without hydrophilic groups, so that the whole material is more hot water-resistant and not prone to swelling; the calcium-zinc composite stabilizer is hydrotalcite treated by a coupling agent and a beta-diketone calcium-zinc stabilizer, water cannot enter the calcium-zinc composite stabilizer, and non-hydrophilic silicon dioxide is adopted as a filling agent of the calcium-zinc composite stabilizer, so the hydrophobicity is also enhanced; and the PVC cable can be soaked in 100 DEG C hot water for 1000 hours, the electric wire does not swell, the voltage resistance is 2 KV/1 minute, and the PVC cable is resistant to voltage and does not
