Rail ladle car is material truck It is also called slag receiving car, ladle car and transition ladle car casting Electric rail car commonly used for transferring steel ladle, iron ladle and molten iron ladle in the industry. This car has high requirements, because the object pulled is a ladle, and the temperature of molten steel is generally one thousand The temperature of inclusion is also five hundred The ambient temperature is fifty Degrees, sometimes in one hundred Multiple degrees, so this flat car needs to electric machinery The reducer is well separated heat treatment To prevent excessive temperature. Relative slag collector Cable The service temperature of the cable of the steel car and the cable of the transition car is 50 ℃ or 100 ℃. Conventional ordinary cables YCW, RVV-NBR, JYFF cannot meet their high temperature requirements, so cables must meet both high temperature and high tension.
The following types of slag truck cables, ladle car cables and transition car cables are available for customers to choose from:
|
Round: copper core hybrid rubber insulated and corrosion resistant sheathed flexible cable for steel car
|

Cable usage characteristics
Rated working voltage U0/U is 0.6/1KV;
The long-term allowable higher working temperature of cable conductor is 90 ℃ and 180 ℃;
When the cable is short circuited (no more than 5S for a long time), the higher working temperature is 250 ℃;
The small bending radius of the cable shall not be less than 6 times of the actual outer diameter of the cable.
● Structural design
Conductor: ultra-fine bare copper wire twisted into bundles
Insulation: silicon butadiene
Color: black core wire continuous white number plus yellow/green ground wire or color distinction
Cabling: filled tensile PP rope, small pitch stranded wire
Internal protection: silicon butadiene
Reinforcing layer: Kevlar weave
External protection: silicon butadiene
● Product features
The overall load-bearing braiding prevents unnecessary twisting of the cable and forms the so-called spiral effect
Double jacket structure, more stable performance and longer service life (3-5 times) than ordinary cables
Fine stranded bare copper wire makes the cable more flexible, continuous and durable
Tension elements and torsion resistant layer are added to prevent cables from twisting and cracking.
Soft, good bending performance: meet the requirements of small radius of curvature of the mechanical guide wheel;
High tensile strength: the use length of the cable in the winding drum is relatively long, and the friction force of the winding drum is very large, so the tension on the cable in the use of moving back and forth will be very large, which requires a strong tensile strength of the cable, and the core wire will not break in the dragging of the cable.
Balanced cable structure, long service life, 3~5 times longer than ordinary YC reel cable, high cost performance
