SPN correspond to the English term Single Phase Node. Equivalent to the Spanish term phase. The phase term in domestic premises or homes means you have a single phase alternating current. Usually contracted power in homes is up to 10kW. The difference with the phase installations is that these can be divided into three phases, namely three alternating currents. The instalaciones-phase may also be divided into parts. Facilities include single-phase 3-wire cable 1. phase (black or brown cable) that is providing electricity. 2. Neutral (blue wire) is responsible for the electricity back where it came from creating a circle. 3. Physical cable (two colors) protects the energy absorbing phase of their environment, in some cases this third cable is not used, but isrecommended it for security. 1. In the image-phase power system three-phase power system 2.

ABS material (acrylonitrile butadiene styrene) is a type of thermoplastic that is very resistant to impact or shock.

Its applications are several, for example is a material widely used in the manufacture of interiors or components of cars such as moldings, as well as in products for domestic use such as toys, tools, housings of electrical devices etc.

One of its most important characteristics is its great tenacidad in almost all types of temperatures.

Being a very hard material has good chemical resistance, low water absorption and high resistance to abrasion, where other types of plastics would be more brittle.

This type of material is becoming very famous in the particular field and widely used due to the great growth in the sales of domestic 3D printers, the main printing raw material.next to the PLA.

Identification of ABS
Parts that are made of ABS material must be marked in accordance with ISO 11469 (DIN 58840).
