Find out how much current the motor draws, then look up wire tables to find out the size of wire. Ask an electrician if you are not unfamiliar with this because working at 6.6 kV is definitely lethal for the unqualified.
How to calculate a cable size of 3kw motor
cable size for the 90kW motor is 3CX150sqmm aluminum cable
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
XLPE cable has high electric strength,mechanical strength,high-agcing resisting,environmental stress resisting anti-chemical corrossion,and it is simple construction,using convenient and higher operating of long term temperature.It can be laid with no drop restriction. Various of flame-retandant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide,silance and irradiation crosslinking).The flame-retardant cable covers all kinds of low-smoke low-halogen,low-smoke halogen free,and non-smoke nonhalogenated and three classes of A,B,C. Some of special XLPE cable can be manufactured according to ther other standards required by customs. XLPE cable having higher long-term working temperature and greater current rating,at the same environment XLPE cable may be reduced size(nominal cross-section)1 or 2 class in comparison with paper
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
How to calculate a cable size of 3kw motor
If it's a 380 v 3-phase supply, the current is up to 300 amps which could be supplied over a short distance by XLPE cable with 70 sq. mm cross-section conductors.

Incomplete data: To have an accurate result - please provide the following; 1. Voltage Rating - Low Votage or Medium Voltage Applications? 2. Efficiency 3. Power Factor 4. Distance - One way distance from source 5. Location and method and arrangement of Installation 6. Allowable or acceptable voltage drop 7. Type of cable - PVC or XLPE cable with same size has different ampacity
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
The NEC has a table that shows what size cable to use with each amperage and where it can be used.
The cable size depends on a few factors, such as the supply voltage, the method of starting the motor, (direct-on-line, or star delta) and the length of cable required to compensate for voltage drop. Also, if the cable is copper or aluminum.110 kW motor has a rated current of 200 amps at 415 volts, so the correct copper cable size would have a cross-sectional area of 75 square mm., if the motor is started direct-on-line.At 660 volts, the rated current would be 118 volts and the cable size would be 35 square mm.
To answer this question the voltage of the motor must be stated.
