Abstract/ Executive Summary:

The project was undertaken to attempt to find out the use of jute as an insulating material on electric cable. Voltage dividing method was used to measure the volume resistance and surface resistance during 1980 in the physics department of BJRI. In this project the volume resistance of jute powder impregnated with pitch in the range of 1X 10^9 to 10X10^9 mega ohm with measuring voltage of 1000 volts was found out using multi mega ohm meter type MOM II. The result showed that the resistance increased i.e. the dielectric constant decreased when jute powder was impregnated with pitch in the lower range of voltage 100-50V. So jute powder impregnated with pitch could be used as better insulating material than pitch itself. The result may be commercially used in the electrical cable industry.

Keywords: Jute powder, Dielectric constant, Volume resistance, Pitch

Start Date: 01-01-1980

End Date: 30-06-1980

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

1. Development of a method to measure the dielectric constant of jute products.

2. Measurement of dielectric constant/volume resistance of jute powder impregnated with pitch.

Methodology:

Measurement of volume resistance of jute powder impregnated with pitch was done instead of measuring dielectric constant. Knowing the volume resistance it is also possible to have an idea about insulating properties of jute powder. For volume resistance, ‘Multi – megaohm-meter’ type MOM II was used. It was the apparatus for the determination of volume and surface resistance in insulating materials. Voltage dividing method was used to measure the volume resistance from 10X10(9) megaohm with a measuring voltage of 1000 volt. Two types of samples with (2cmX 2 cm X0.5 cm) sizes were made, one with pitch and other with jute powder impregnated with pitch at the ratio 6:1 and 5:2

Achievement/Findings:

From the result it reveals that the resistance increases after mixing the jute powder with pitch that means it reduces the dielectric constant. So this mixture can be used as better insulating materials than pitch itself. Especially in the lower voltage range 100-500V, the resistance is much higher.
