At the start the production of the company comprised merely electrical heating appliances for domestic use. When the industrial need for heating apparatus began to make itself felt, the range was extended to include also large immersion heaters, cireulation heaters, retorts, etc. The amalgamation in 1922 with the Hj. Lofquist Electric company brought about a further extension, in part by the acquirement of the very valuable patents of the latter firm of high and low tension steam boilers, electric furnaces for hardening, annealing and smelting, etc., distillation apparatus of capacities from 1 to 100 litres per hour.
The scope of the manufacturing thus covers practically the entire electrical heating line. Up-to-date works and equipment, competent engineers, and a well-trained body of workers are an assurance that the goods turned out by the Volta company are of the highest quality.

The Volta electric storage battery range is the result of long experiments, and embodies many improvements not found in any other appliance of this kind. It is equipped with two intercommunicating cooking places, consisting of two connected cast iron cylinders having a joint battery of 500 watts, easily interehangeable. This battery stores up energy during the night hours, enough for cooking purposes for a family of 6 to 8 members. The range is equipped with a hot water heater and a baking oven of practical design.

The Volta salt-bath furnace produces a uniform and constant heat, the exact required heat for the steel. Tension uniform. Protects the steel from oxidizing.
Data required When inquiring for salt-bath furnaces, the following data should be given:
1) Current available, 2) Voltage and cycles, 3) Size of crucible, 4) Maximum hardening temperature, 5) Capacity per hour or working day.
It should be noted that the highest temperature for which these furnaces are made is 1,300° C.

General From a modest start the Sievert Cable company has advanced to the position of incomparably the most important manufacturers of cables and insulated conductors in the North of Europe. The present large works have come into being to meet the increased demand, and each department is equipped with specially designed machines and appliances for the manufacture of the Sievert products. By means of such efficient aids to the production, the company's cables and electric wiring materials have acquired the highest reputation, all the more so as they have proven their worth in actual service under the severest .conditions. From comprising chiefly vuleanized electric wire the production has by degrees been extended to wire and cables for all electric purposes, such as lighting installations, apparatus and machines, telephone and telegraph plant, electric power transmissions, etc.
Sieverts have devoted special attention and enormous expense to the establishment of the department for high voltage cables, and this has led to improved methods in the production. It can be asserted, without fear of exaggeration, that the works, with their present resourees, stand in the very forefront of the world's cable industry. The company, too, holds several world's records especially regarding submarine cables both in respect to laying depth of high tension cables, and continuous length of such cables.
