Abstract

The invention discloses single-core cable insulating rubber for a low-smoke and zero-halogen flame-resistant rail vehicle with rated voltage of 3000V and temperature resistance of a 125 DEG C level. The single-core cable insulating rubber comprises the following components in parts by weight: 100 parts of crude rubber, 2-6 parts of organic peroxide curing agent, 1-5 parts of auxiliary curing agent, 1-4 parts of coupling agent, 3-8 parts of anti-aging agent, 10-25 parts of strengthening agent and 5-10 parts of plasticizing agent. The single-core cable insulating rubber has excellent insulating property and is very soft. A cable produced by the rubber is soft and is easy to bend, install and lay. The single-core cable insulating rubber has excellent insulating property, can continuously and normally work at voltage of 1000V and high temperature of 125 DEG C, can resist climates, ozone, heat, ageing, acid, alkali and fuel oil well and has low-smoke and zero-halogen flame resistance, environmental protection, safety and long service life.

Description

technical field [0001] The invention relates to a cable insulating rubber, in particular to a single-core cable insulating rubber for rated voltage 3000V, 125°C, low-smoke, halogen-free, flame-retardant rail transit vehicles. Background technique [0002] With the development of localization of locomotives, the cables for rail vehicles have gradually shifted from relying on imports to mostly domestic production. At present, they can meet the rated voltage of 3000V and the low-smoke, halogen-free, flame-retardant single-core cables for rail vehicles with a rated voltage of 3000V and a resistance to 125°C. However, there are still few on the market, and the existing problems are: the increase of the pressure resistance level leads to the increase of the hardness of the cable rubber, and the small bending angle is difficult to meet the standard, which brings difficulties to the installation and laying of the cable on the rail transit vehicle, and cannot fully meet the requiremen...
