This testing machine is a low-temperature stretching, winding, automatic and intelligent testing machine developed by our company. The equipment adopts human-machine interface control, which makes intelligent operation more convenient and simpler. It is also equipped with a micro printer for printing tests. data. This equipment includes four pieces of equipment: high and low temperature test chamber, electric low temperature tensile test device, low temperature winding test device, and low temperature impact test device.
The high and low temperature test chamber simulates high and low temperature environments and is widely used to determine the adaptability of electrical and electronic products to high and low temperature environments (especially the changes in the electrical and mechanical properties of the product). It can also be used to check the specimen's resistance to certain Ability to corrode.
The electric low-temperature tensile testing device is suitable for tensile testing of polymer materials, wires and cables, rubber, and plastic insulating sheaths at 0 to -40ºC/-60ºC/-70ºC. Its structure and performance meet the GB/T2951-2008 standard requirements.
The low-temperature winding test device is generally suitable for circular insulated wire cores with an outer diameter of 12.5mm and below and sector-shaped insulated wire cores that cannot be prepared as dumbbell specimens. If specified in the relevant cable product standards, the test shall be conducted on large-size insulated cores. Otherwise, large-sized insulated wire cores should be subjected to low-temperature tensile testing.
The low temperature impact test device is suitable for all kinds of PVC sheathed cables, regardless of the insulation type of the insulated core. If specified in the relevant cable product standard, it also applies to the polyethylene insulation of unsheathed wires, flexible cords and flat flexible cords.
The PVC insulation of sheathed cables is not directly subjected to low temperature impact testing.
Beautiful appearance, safe and reliable;
Easy to read, stable and high precision;
No manual calculation required, easy to operate.
