Product Name:low temperature tensile testing machine

Product category:Wire & Cable Test Equipment

Product Description

Scope of application: this instrument is used for the tensile test of the insulation sheath of polymer material, wire and cable, rubber and plastic in the environment from 0 degrees to -35 degrees. Test standard: meeting GB/ t2951-2008 \VDE and other related standards.

Test principle:

1. The drawing machine is composed of dc motor, transmission parts, specimen chuck and sensors.

2. The electrical control cabinet is composed of dc power supply, voltage regulator speed regulating system, digital display system operating platform and various indicating systems.

The speed regulation system of the voltage regulator can realize the stepless speed regulation of the dc motor, and the control operating system can realize the positive and negative rotation of the motor.

The digital display system can measure and display the accurate tensile speed and length, and the display number can be reset. When the specimen begins to stretch, the display displacement is displayed. When the specimen is pulled, the displacement number stops at the moment of breaking. When the movable chuck of the test piece moves to two positions, it will stop automatically when it hits the travel switch to prevent the mechanical part from crashing.

Main parameters:

1. Motor power: 90W, external type

2. Maximum tensile strength: 220mm

3. Drawing speed: 20 ~ 30mm/ min

4. Type of chuck: self-tightening type

Number 5, sample specifications: Ⅰ, Ⅱ dumbbell

6. Data reading: read elongation directly

7. Overall dimension: 425 * 245 * 280mm

8. This test machine can be used with low temperature box
