In this transformation process, high-voltage mining cables play a crucial role. This article will explore the importance and technical characteristics of high-voltage mining cables in the construction of smart grids.
Technical characteristics of high-voltage mining cables
According to the provided webpage content, the production execution standard for high-voltage mining cables is MT818.13-1999, which specifies the technical requirements for the fixed laying of flame-retardant power cables with copper cores for coal mines with a rated voltage of 10kV and below. The following are several key technical characteristics of high-voltage mining cables:
1. high operating temperatureThe maximum allowable working temperature for cable conductors is 90 ℃, ensuring stability and safety under normal working conditions.
2. Short circuit high temperature resistanceIn the event of a short circuit (with a maximum duration of no more than 5 seconds), the maximum temperature of the cable conductor does not exceed 250 ℃, providing protection for the cable under extreme conditions.
3. Temperature requirements for layingThe cable laying temperature shall not be lower than 0 ℃, ensuring normal installation and use even in low temperature environments.
