Not enough to worry about as long as your wire is sized properly to 40 amp. 6 meters isn't very long
Your question cannot be answered, as we do not know what type of wire the copper is coated on, nor do we know how long the wire is. But, let's assume that it is solid copper # 10 wire 100 feet long. The voltage drop is zero when there is no electricity flowing through it. (That is, 'current', measured in Amperes, or just Amps.) If there is, say, 1 Ampere of current, the voltage drop is close to 1/10th Volt in the 100 feet. If there is, say, 15 Amperes of current, the voltage drop is a tiny bit over 1-1/2 Volts. If you double the wire's length, the voltage drop also doubles, and if the current doubles, the voltage drops also doubles. Or, as in my example, above, if the current rises by 15 times, then the voltage drop rises by 15 times.
The wire resistance is proportional to the length of wire divided by its cross-section area. The voltage drop is proportional to the resistance times the current.
I would recommend no smaller than #8awg copper. This is derived by 8awg copper ampacity of 40 amps multiplied by 80% load rating to get 32 amps. Then calculating for voltage drop over this distance shows a drop of 5.9 volts or 2.5% which is negligible so not accounted for. So like i said no smaller than #8awg copper.
A #14 copper wire with an insulation factor of 90 degrees C is rated at 15 amps. To answer your question for voltage drop at 200 feet a voltage needs to be stated. Assuming the voltage of 120 is used to maintain 15 amps at the distance of 200 feet a #6 copper conductor will limit the voltage drop to less that 3 percent. Assuming the voltage of 240 is used to maintain 15 amps at the distance of 200 feet a #10 copper conductor will limit the voltage drop to less that 3 percent.
This is a voltage drop question. A voltage at 30 amps needs to be stated to answer the question.

Voltage drops need to be checked with a volt meter. Depending on where the drop is thought to be, the meter can be connected an wiring plugs to find where the drop is.
A splice has a minor additional resistance associated with it, but the main reason for voltage drop will be length. The smaller the wire diameter, the higher the resistance per unit length. The type wire such as stranded or solid or copper and aluminum also contribute to voltage loss in various ways.

When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
IF USING A COPPER AT 105 DEG. CELSIUS - 70 FT. ONE-WAY LENGTH: TO GET AT VOLTAGE DROP = 3.72% AT 25 AMP LOAD ---- USE #1 AWG TO GET AT VOLTAGE DROP = 2.94% AT 25 AMP LOAD ---- USE #1/0 AWG TO GET AT VOLTAGE DROP = 1.85% AT 25 AMP LOAD ---- USE #3/0 AWG
The wire resistance is proportional to the length of wire divided by its cross-section area. The voltage drop is proportional to the resistance times the current.
Because of voltage drop, 4 awg copper would be recommended for that distance run. <<>> A #1 copper conductor will limit the voltage drop to 3% or less when supplying 50 amps for 200 feet on a 110 volt system.

Voltage drop depends on the size & length of the wire and the wattage of the bulbs. If they make an LED replacement bulb , you would hardly notice the voltage drop.
