Vertical Cold Chamber upto -86 deg
Cold chambers are and integral part of any cable test laboratory. They are helpful in performing cold bending, cold elongation and cold impart tests as per latest revision of IEC-60811 5 and 6 series. Techtrivial has many different designs and sizes for vertical cold chambers ranging from -15 degree Celsius to -86 degree Celsius.

Multi Cell Ageing Oven (IEC & UL2556 Compliant)
Multicell Ageing Ovens (with or Without HMI-PLC control)
Each Cell is a complete instrument in itself i.e., fitted with individual Temp. Indicating Controller, Air Flow Meter, Air temperature controller and an
Hour Meter. This enables the user to test different type of samples at desired temperature and duration, depending upon test requirement of end users
& testing authorities.
The instrument consists of the following:
• Double walled chamber with inside chamber of thick aluminum sheet. Size of the chamber is 10 cm x 30 cm
• Digital Temp. Indicating Controller with sensor. Temp. range 0-200 ± 2 o C
• Digital Flow meter for monitoring the volume of air passing through the chamber.
• Air inlet nozzle for the airline or air compressor.
• Specially Designed heaters to heat the air before it enters the cell
• Separate temperature controllers for air temperature control
• Air turbulence fan with motor to rotate at 60 RPM (Air source has to be provided by User)
• Specially designed cover to hold three to five test samples in each chamber.
• Timer System to record the total time of test.SKU: n/a -

Hot Air Oven (With or without Air change)
Our Ovens are sturdy, with double walled construction. Inner chamber made of
ALUMINIUM or STAINLESS-STEEL sheet. Outer chamber is made of stainless steel
or galvanized steel or mild steel sheet and are duly powder coated.
The gap between the walls is filled up with special grade glass wool for proper
insulation to avoid heat losses. Inner chamber has ribs for placing the shelves at
convenient levels. Supplied with 2 or 3 removable shelves. The oven door is mounted
on heavy hinges with a handle. Door is duly insulated .
Temp control uses Thermostat ,On/Off Control ,PID Control ,Microprocessor control
*Please specify the kind of controller and accuracy required at the time of ordering.SKU: n/a -

Cold Bend Test | Cold Impact Test
IEC 60811-504 describes the cold bend test method for cables under low temperatures. The cold bend test on cable is only possible upto a maximum diameter of 12.5mm. The test is mainly conclusive to understand the flexibility and strength of plastic used over cable under low temperatures.
Whereas cold impact test on cables is performed according to IEC 60811-506. This test is mainly designed to simulate the plastic’s capacity to resist mechanical shock under cold environment.Here from a certain height, mandrels of specific weight are dropped on the cable.

Optical Profile Projector for cable
We have all range of Profile projectors suitable for cable and automotive manufacturing sector. Market is flooded with inaccurate and camera based profile projectors that are actually not compliant with Vision systems but still expansive as them.
Automatic profile projector for cable used in Cable Dimension measurement of any shape of the cable. Available with Accredited calibration master, color measurement, from 36 mm to 108 mm diameter samples.IEC-60502-1 and EN 50525 describes the requirement of exact dimension measurement of the insulation, inner jacket and outer jacket of a cable and it’s core.
Where you actually lose money?
- Having higher Insulation wall thickness due to the operator’s running safety margin
- Ovality of extrusion head setting causes the inhomogeneous spread of compound over the conductor.
- Due to higher core diameter, each next process of cable manufacturing such as stranding, taping, braiding, armoring, shielding, inner sheathing, outer jacketing takes a minimum of 0.05% to 3% of extra material.
- An average-sized Cable manufacturer who consumes 10 Million euros of plastics per year losses around 300.000 € just because of non-optimized dimension of cables.
We also supply all the measuring components calibrated by NABL accredited master instruments so that accuracy and uncertainty are never a concern for our clients.
