Answer: For thinner insulation design.

Taking UL AWM 1061 semi-rigid PVC insulated wire as an example, it has the following characteristics and applications:
1.Characteristic:
(1)Temperature and voltage ratings: The rated temperature is 80℃ and the rated voltage is 300V, suitable for general low voltage, medium low temperature electrical environments.
(2)Conductor material: The conductor is made of single or twisted 30-14AWG tin plated or bare copper, which can meet different conductivity and flexibility requirements.
(3)Insulation characteristics: Semi hard PVC (SR-PVC) insulation is used, which is relatively thin and has a smaller outer diameter than some ordinary PVC insulated wires of the same wire size, such as UL1007. This insulation material has characteristics such as acid and alkali resistance, oil resistance, moisture resistance, and mold resistance, and complies with ROHS environmental standards.
(4)Processing performance: Using standard insulation thickness, it has the characteristics of easy wire cutting and stripping, making it convenient for wiring and connection during production and processing.
(5)Flame retardant performance: Passed UL VW-1 and cUL FT1 flame retardant tests, it has good flame retardant performance and can effectively prevent the spread of fire.
(6)Color options: Available in a complete range of colors, including red, black, white, yellow, green, etc. Other colors can also be produced according to customer requirements to facilitate differentiation of different circuits and functions.

2.Application:
(1)Internal connections of electronic devices: commonly used for connecting power and signal devices within electrical, electronic, instrumentation, mechanical, and electronic equipment, such as the wiring connections between internal components such as computers, printers, copiers, etc.
(2)Internal connection of household appliances: It can be used for the internal wiring connection of household appliances, such as refrigerators, air conditioners, washing machines, etc., to connect various electrical components and transmit power and signals.
(3)Internal connection of buildings: suitable for connecting some low-voltage electrical systems inside buildings, such as lighting circuits, small electrical socket circuits, etc.
